TrickFlowTech

The Trick Flow heads are brand new castings (thicker than stock castings, better spark plug location in the chamber, 13.5 degree valve angles) not ported factory casting, and we use high quality components in our heads.

That was my point earlier...CARTEK heads are customers heads that CARTEK sends
out to have ported and to have the valves and springs installed. I've been to CARTEK and
when i was there they had boxes stacked on top of their flow bench..lol. I heard, but not
totally sure that Pat Musi does CARTEK's porting. Julio is a great tuner but they don't port
in-house. They dont have the overhead cost of casting heads like TrickFlow, AFR, or
Edelbrock which are cheaper than CARTEK. Personally NO HEAD cost $2700 neither custom castings or otherwhise. Just way too much!!

afr are good to me,low and midrange torque as well

It's a shame people don't believe a head that flows more air everywhere will actually make more TORQUE everywhere, than a head that is simply small.

In the real world of back to back dyno testing, our results have been the same as yours, bigger, higher flowing heads made more power at every RPM point irregardless of cam duration or lift.

I am sold on my TFS 215, my car picked up more HP and torque from 2000 rpms to 6500 rpms, no comparision vs Lingenfelter 243 cnc heads that were on my lpe built 383. I find it very hard to belive that anyone can port a head "that" much better than lingenfelter when it comes to a 243 castings. my 383 makes more power than most 403, 408 and some 427's and it all started with tfs 215 heads from TEA and a great package from Ron at Vengeance all assembled and tuned by Carmen at the Vette DR's.

I have Trick Flow 215cc heads on my car and it helped my 1/4 times dramatically. I picked up 5 mph+ on my trap speeds and dropped my best ET .3 seconds. Now I need a bigger set of headers so I can reach the true potential these heads offer. Just save up the extra pennies and get these heads. You can't find a better set of heads.

Best ET ran last sunday SEP 7th:

R/T .041
60 1.723
330 4.919
1/8 7.410
MPH 97.93
1000 9.537
1/4 11.289
MPH 131.42

AFR, ETP, TFS CONSISTENTLY make big HP. Dont fall into the trap where a sponsor makes these big numbers with there new heads. Ive seen this happen & everyone goes out and trys these heads out and they dont come close to the numbers the sponsor makes. My point is go with something proven over & over again.
I had AFR 205s. I liked them alot. If I was going H/C 346, Id go TFS 215s this time.



To the people posting your ETs & MPH...why dont you include you raceweight & DA you were racing in too. Lots of these guys are stripped down cars.

AFR, ETP, and TFS had to start at zero when they were introduced into the market. Based on what I see, don't rule out the PRC 215 aftermarket casting.

Our customers prefer AFR and TFS usually. Both have solid reputations of performance and quality. The AFR 205 was the best you could do for a while, then the TFS cam along and the two of them battle it out for king of the hill. Those are the two better heads on the market with quality and performance you can count on. If one of my customer doesn't have the budget I tell them to look for a used set. How much do used sets sell for? That tells you how good the head is. How well does it hold its resale value?
Used AFR's go quicker than you can blink an eye and I really haven't seen used TFS's for sale. So what does that tell you? Bargain heads are a dime a dozen used but AFR's will get 1600-1800 every-time. You would never see a used set of AFR's for $1200... they would be gone instantly.

I would go with the afr 205's

Brian...i agree with you..but it's not just about flow, it's also about
air speed as well. You can have 2 sets of heads that flow about the same amount but the head with a smaller intake runner will have a torquey low end over
a larger runner head. Also larger heads are more picky about cam choice.
Where smaller heads will make good power with just about any cam within reason. I experienced this a few times on my car. And i believe you know the guy in south jersey and his first initial is " J" who tought me all about
runner design.
BTW...i emailed you 3 times about sending you my 241 heads from my 2002 SS to have you do a killer stage 1 or stage 1.5 port job. I was told to come to you for what i'm looking to do.

CraZee ZO6

^^ he prolly hasnt responded cause its obvious is not worth porting your 241 heads when you can just get the TFS 215 head or the as cast head for less money. Port job would cost you that alone

How would TFS 215's that i would have to have someone port them cost less
than just having my 241's ported? Plus the cost for a set of rockers to fit the TFS's.
Overall the TrickFlows wouldn't be cheaper, not by a long shot. Besides TEA post on their site about porting stock LS1 and LS6 heads. Anyway he's a company that does business
with the public, meaning he should always respond to a customer's questions.
Thats a major part of doing business with the public. Texas Speed emailed me back in less
than 24 hours...Since i'm not going with a huge head/cam setup i just wanted my
stock heads ported....there's no reason why i can't get a responds back no matter what.
It's all cool though...I'm going somewhere else for my head/cam needs.

I've been to CARTEK on several occasions. Mike does all there porting in house @ CARTEK.
Also, you're better off calling TEA. I've had much better luck with them by phone. Good luck.

BlackNiteWS6

^^oh ok i can call them tomm. i only emailed TEA cause i know how busy they
are. When i was at CARTEK getting my car dynoed they used to send out heads to be
ported and they used their porting table and flow bench to stack boxes on them. But thats
cool they port in-house now....I know Julio does great tuning as well. Thx for the update. I forgot to add...now that they port in-house there's noway their
heads should cost $2700. AFR, TFS, and other use custom castings plus they
port them and they are still cheaper than CARTEK.

I think I am going to go with AFR... I may have a lead on a set of used ones locally... If not... I think I am going to Call Tony @ AFR... for a set of milled ones 61cc with good springs.

Why AFR 205. I like the mid range torque... as cast it seems to me they are great heads...

Only reason I shy from TFS heads are all the extra valve train part that will be needed... that is extra cost... AFR uses stock rocker and etc...

CraZee ZO6

the TFS 215 will make more power than the afr everywhere and a good amount too.

trust me I know people who went from afr 205s to tfs 215s and saw a big improvement.
they are worth it but its up to you in the end.

just my .02

just go with the AFR 225's make great power and u have some room to grow

Other reason... I am kinda iffy against the TFS... a friend of mine has a 445 RWHP camaro M6 with TFS heads... makes great dyno numbers...

Cant beat me on the Street... I know ... I know driver, which is more of the reason... But still... I kill him out the HOLE... and he doesnt have enough to catch me on the street.

Any LS head (including GM) with bronze guides will suffer premature guide wear if stock rockers are used, this is the only reason why TFS says to use roller rockers. We've taken apart plenty of competitors heads whose customers used stock rockers and the guides have to be replaced every time.

Stock GM heads use powdered metal guides and they generally do not wear with stock rockers.

Good luck with your combo.
