I'll like to see them results....

 

The internet is always available! Plus quite a few are on fb and every time i try to find a post, the refresh makes sure that never happens.
I really like trick flow, but keeping up with the times is necessary and prc 225 as cast out of the box are ready to rock with no extra work needed.

 

Quite funny to me.... the guys over at ls1 excitement was running PRC heads on they turbo Formula. Anyway it ended up costing them a motor and alot of money.... those LSX blocks are not cheap.

 

Im sure it was all TSP fault too. -_-
I can say recently ive seen way more castings not PRC fail on social media.
Too bad Paul Harvey has passed.

 

Beating them at what exactly? There's a lot of things to consider. Valve angle, deck thickness, area under the curve, port velocity (which is higher with a smaller port head, and the TFS has a smaller port). I'm assuming you mean peak numbers..

Was there a back to back test where someone tried each on the same combo?


Don't get me wrong, I'm a texas speed fan for sure, they have top of the line NEW equipment and a **** load of it. They do tons of testing and turn out killer products for a lower cost than anyone else. I just am interested in seeing the testing and what the differences are. For the past few minutes I tried searching TFS 220 vs TSP 225 and similar things with no results.

I don't mind someone saying google it, but can you point us toward what to google?

 

Oh and those heads are $1900 on their website. Not $1500

I guess you mean you can get them bare for 1500, trick flow are 1400 bare..


No doubt both are excellent heads, but I have personally put together a top end for a guy with the trick flow 220s and after seeing what it ran at the track straight off the trailer I have a hard time recommending anything else. Especially at the price point.

Post up the issues you've heard about with the trick flows.

I'm not trying to argue, i'm trying to learn.

 

Valve angle same
Deck thickness nearly the same
Flow numbers favor tsp
Port velocity, up for debate

Basically same builds making more power in quite a few areas but in real world results running better et or PBs.
I try to keep track of the posts i see with failures of any kind and basically a where are they now type of deal. The threads shortly turn into bashing just like this one likely will. But there are some facts to be gleaned.

Again, it was posted in here earlier, take trick flows then send to tea for valve job. Why? Because they arent as good out of the box? Who says that about prc aftermarket heads? Quite a few big name youtube players switching to tsp heads also so thats more public and searchable. Tsp heads that break records? Off shelf out of box heads. No extra mojo needed. No sending off to another company. Bolt on, go.

 

So basically the TSP has more work done to them out of the box and the trick flow need a valve job to match the work done on the TSP?

I wonder how the trick flow stack up with equal work done to them as done on the TSP. Best guess is pretty similar, probably come down to a total cost or brand preference thing at that point.

The trick flow are a hair cheaper that could go toward the valve job.

Do you know who has the thicker deck?

The trick flows I put on my buddies car were out of the box stock. With a fast 92 on it, stock short block, it ran 6.8s off the trailer with a torquer cam, no donkey dick cam, only had a 3600 stall too.

 

If you paid me some money to run a name of a cylinder head on side my car I'll do it. Texas speed sponsors alot of racers including Cleetus, Ray Bulach before he sold his car, etc... Ray once was running some TFS heads on his car UNTIL Texas Speed wanted to sponsor him. Both Cleetus and Ray had some serious turbo 6 speed cars.

Roddy Coleman and James Day both hold records in naturally aspirated forms LS motors.... PRC headed motors were left behind.

 

Damn tusky you got a encyclopedia in your head

 

I try to remember stuff Jake. I dont really pay attention to those turbo cars etc. Anybody can put a turbo on a car and be fast. However, I pay close attention to naturally aspirated builds even if i dont post on a build thread on here i have checked it out for my own research. I also go to every LS fest and i know what i seen there as well.... its a company thats in the LS cylinder head battle that outflows both TFS and PRC (cathedral) on the flow bench but no naturally aspirated track numbers yet out those heads as far as i have seen. And its not Mast by the way.


Remember people lie and numbers dont.

Also been meaning to tell you that I KNOW NOW after this past LS fest that SOME aftermarket LS3 heads are a joke. I seen alot of big name aftermarket LS3 head get beat by a factory casting LS3 head Cnc'nd by BLAH BLAH.....

Sidenote: James Day Camaro runs 9.40 in the quarter with some TFS 235s, hydraulic roller, fast intake on pump gas and its not tin can like some others out there. Car could be faster if he found away to keep the nose down as well.

 

$1700 is about the limit for me, even that I'm not sure about. Since I'm not going to be putting the car together until probably April, I'm going to keep my eyes open for a deal. I found a set of AFR 225s for $1350, but they have 2.08" intake valves so it's not going to work. I'm really kicking myself for not buying those PRC 225s for $1000 I saw a couple months ago now.

 

Tsp holds at least 3 records for na sbe stuff and the ones that beat their 4th gen is running prc heads also. And some of those passes no one has come close to yet.

Ive seen multiple trick flow castings broken in the same spot along with now 2 customers that got trick flow ls3 heads and had the valves taco because as tfs put it when i talked to them
"were they running a helluva lotta boost?"
"How much is a helluva lot?"
"Over 15lbs"

They were running in the 20s and apparently you have to upgrade them to the manley severe duty valves but they dont advertise that anywhere on the site etc. Thats at least $320 more on top.

Also i seriously doubt those guys are running out of the box tfs that you like to tout often in every tfs thread tusky.

Seriously go back and look i used to recommend them a TON but having such failures and no info caused me to look at different affordable options.

If you compare the tfs 220cc heads with the ti retainer option then they are the same as the prc and they only rate their springs to .600.

You want a sponsorship talk to the heavy hitters you know. Im sure they would be happy to help ;-)

 

I have about 20 400 plus cubic inch recipes wrote down in my personal notes. All 6 speed F body cars.... out of that 20 car field i have wrote down there are only TWO cars runninng PRC 247 cathedral heads. Its only ONE that was impressive to me on a 41X ci combo and that ONE car im referring to only weighs 3000 lbs. However, that car run low 10s all motor with a 6 speed. I dig it.

The red camaro TSP SBE car you referring too weighs like 2600 lbs. Not hard to make a go kart fast buddie.

Meanwhile, its a 402ci combo in my notes running a set of TFS 235s out the box in a 3600 lb WS6 that run 10.3s spinning @ over 132 mph. Matter of factor its thr heaviest car out of my notes but yet one of the only cars trapping 132 plus mph. Most are stuck at 130.....

Im on my way to work but here is some of the combos off the top of my head that i can remember.

All cars below are 6 speed, not gutted out, hydraulic roller and on pump gas. All are fourth gen cars.

403ci, AFR 230s, fast 102 intake #ws6
416ci, LS3 heads, LS3 intake, #ws6
413ci, Mast 245s, fast intake #ws6
416ci, TFS 225s, fast intake #SS
402ci,TFS 235s, fast intake #ws6
402ci,AFR 205s by Mamo, fast intake #Z28
408ci, AFR 225s, fast intake #SS
408ci, TFS 225s, fast intake #SS
403ci, AFR 225s, fast intake #SS
427ci, LS7 heads, LS7 intake #SS
404ci, TFS 235s, fast intake #Z28
418ci, PRC 247s, fast intake # ws6
408ci, PRC 247s, fast intake #ws6
408ci, LS3 heads, fast intake #ws6

Thats most of the combos... PRC wasnt the fastest out the bunch but the 418ci car is probably the lightest....

 

2600? Youre guessing there aren't you? If its so hard to do, why did it take over 8 years to break the record set with some 227cc heads? Cmon man. You want all the credit but dont wanna give it cuz they aint your boys. I get it but those are facts still and records.
The rest of it? Keep your trick flow. I can agree to disagree but there is professional experience and customer feedback behind my reasons as well as so many failures on fb.
But you never said if ANY of those other fastbois are using out of box heads. Im guessing that's a no. So if the PRC are that good and not over 3k then imagine how much better theyd be if you dropped the same amount in em other people recommend with every other head not even as an add on but as a necessity. At some point paying more for the same or less has to mean something.

And your list are the cars you know of. In your words "isnt hard to make 400ci fast"

And how are you categorizing fast? Mph or et? And whats "not gutted"? Man cmon your bringing alot of extra with no validation. You try to make a comparison of ONLY heads on multiple diff cid setups that have much more than just that different. Thats no comparison but ok.

 

No Validation? I have every e.t and weight to each combo above. I sure would like to see one of TFS failures.

 

I'd pick the heads with the best valve guides and valves stock. The TSP heads will come with .660 springs vs .600 for the TF.

 

Et means power?
And all you have to do is search. Lots of pictures. You are up on all the rest, why not that?

 

I am up on all with the rest but you right as always. PRC heads are the best of the best. The fastest cars in world ive seen are running those Texas Speed heads.

 

Im not always right.
Here are a pic of the tuliped valves. Customer had to get the severe duty from manley for $360 or so. He was definitely not happy.
That was when i verified and called tfs and they said what i said previously. its definitely not advertised anywhere either.
