Ordering one or the other within a couple days...any opinions on which would be better? I know they won't be much different, but if one has a slight edge over the other, then i'll go with the best. I have a set of roller rockers so that's not a problem with the TFS. the ET heads show better low lift numbers but require a custom rocker pedestal which is another $100, but thats not really a problem. My setup is an 02 SS M6, running an MS4, FAST 90, ls7 lifters, all other supporting mods, 4.10s, etc...i had my mind set on TFS but now i'm starting to lean toward the ET heads. i've heard nothing bad about them yet. What is everyone else's opinion? Thanks! Jared

I say give the TFS heads a try. one of the local tuners has those heads on his vette with a medium size cam and made almost 500 rwhp.

If money is no problem, stick with ET heads.

I talked with Mike @ New Era Performance and asked him this very question. He sells and has installed both heads on customers cars. He told me that performance wise they are the same but he likes the ETP's better. He said if you were to look at them both side by side that most people would take the ETP's because they are an absolute work of art.

That was enough to sell me on the ETP's. I have seen them up close and they are absolutely beautiful.

If you want to hear it from him yourself then you can call him at 585-865-1832 or email them through the website:

I recently put on a set of ET215s and I've been happy with the improvement of 24rwkW (32rwhp) with my small-mid sized Comp 222/224 cam in a Ls1. I will be putting a larger cam in later in the year, as the heads are wasted with that small stick. The on-road improvement was very good, especially the torque in the mid-range and the top end is a lot stronger too.

I think any of the ET, TFS, AFR, etc, are a great thing, as they are all designed to be better than the oem heads.

Cheers,

Macca

the etp head is a much more advanced looking head but number wise u wont see a diff. they both perform very well. when i put my tfs 215's on with my torquer 2 cam and a fast 90/90 i picked up 79 rwhp and 46 rwtq. htey performed very very well imo. a guy at my work went with the etp's and torquer v3 and only made a few more hp/ tq. but that could just be the varience in the cars themselves.

one thing is u will have a little more ptv with the etp head with the 11* valve angle as oppossed to the tfs 13.5* angle.

I'm a little biased, but I'll say TFS. they work plain and simple. I've seen the ET 215's put down good dyno #'s just haven't seen any ET well yet. no pun intended.

TFS has been proven for many many years now, no need to even question if the head is worthy or not.
cant say one is better than the other.



this would be the only plus between the 2

cant say one is better than the other. they are both good heads

well i talked to thunder and texas speed today about the ET heads and they said it can be anywhere from a week to 6 months before i would be able to get them...they're supposed to call ET monday morning and then let me know. I have the money now to completely finish my car, so if the wait is more then a couple weeks i'm going with TFS. I've also thought about the PTV clearance issue that ls2bait mentioned and I think i'll need it with the MS4 because I want to mill as much as possible for more compression. So basically it will come down to the wait for ET heads.
So how much hp/tq and track times is everyone getting with these heads?

I never questioned TFS. I questioned ETP 215's specifically. Until someone can do something with them on the track NA, They are not as good as the the TFS 215's or AFR 205's IMO.

talk to jeremy over at mph parts ------------> i know for a fact he had a set of 215 et's in stock last week and he can get you the tfs heads also.

I am a TFS supporter, i own a set of the 215's myself. with that said, the valve degree angle is HUGE in unshrouding the valve in the cylinder and allowing more airflow.

Personally, id dig a little more and see what you find. the 11* valve angle and the reputation is promising.

either way you wont be dissapointed im sure

I went with TFS on my 408 just because I've seen how well they did on all the 346's they were out on and because of the insane wait times with ET. The verdict is still out on the ET heads imo. I see a lot of people talking about putting them on these big builds but never see any #'s (maybe everyone's still waiting for their heads). I also remember seeing a few different ET dyno sheets awhile back where the power started breaking up in the higher RPM's .

So far my TFS have been great and have power everywhere.

I just checked the prices at new era's site, and there is like a 45 dollar difference between the ETP's and the TFS 215 heads. So price shouldnt be an issue at all if you looking to buy either one of those heads. IMO of course

I purchased two sets of TFS heads from Ron@Vengeance. The first was TFS 225 for a C6 and it was ready for shipping 1 week after I placed the order. The second set was TFS 235, and it took 3 weeks to have them ready for shipping, probably because I requested custom valves.

Bottom line, delivery times for the TFS heads are proven to be faster.

Here is a write up of a test of some of the best heads on the market. Hope this helps!!

Well I'll have to disagree with your opinion. Sub par quarter mile ET's have nothing to do with the heads. If the heads make decent power then they did thier job. If the ET isn't there then the person who owns the car needs to look at thier stall, suspension, gears, tires, ect and see what they didn't do right. Most poor ET's are because of the wrong gears, the wrong stall size or the inability to hook.

ETP = TFS and both are slightly above afr 205 IMO.
