I spent a good deal of time at the ET booth at PRI, all I can say is we ordered a handfull of them this morning. They are much more willing to do custom applications then the others and the port work is better finished off.
We'll have them ready to ship if you are interested.

The more I read about them, the more I want to go with them for my cam upgrade on my 04 Z06 (LG's X1 cam - 228/232 588/574 114LSA) ...
I hope they do not disappoint....
I would love to hear more people's real world experiences with them...

ETP 215's
My car is an '05 Z-51 4L65E automatic. The graph shows the stock baseline, then first and second rounds of mods.
The first round of mods were LG Pro Longtubes w/3" X-pipe, Corsa Sports, Halltech Stinger and LS2 Edit tune.
The second round of mods were E.T. Performance 215 58cc heads w/cnc rocker rail, Comp 224/228 .581/.588 114+1 cam, F.A.S.T. intake (not ported), Underdrive pulley, and Yank SS 3200 C6 converter. Again, LS2 Edit dyno tune by Jeremy Formato.
As you can see, the mods make a LOT of difference!!! From 311RWHP, to 360RWHP, to 444RWHP. I have been driving the car for a week now to see what we need to change with the shift points, lock-up and tune. I am confident we will get 450RWHP out of it when we re-tune, even with the high stall converter. I think folks will be very pleased with the ETP heads!

The hardware is top notch. The springs and retainers used would be a $400 upgrade on most other heads.
The stock rockers fit and Jesel now makes a rocker system that fits. I believe those are the only options at this point.
My car made 499 RWHP with a 228 - 232 cam and ETP 215s..

As others have stated. They are definitely the current thing and are very popular over on LS1tech. Now that they have been beta tested, we are putting some on cars now and have added them our line up at http://www.synergymotorsports.net/
We finally have true competitor to fine hand worked heads.
Way cool,

One thing I like about the ETs is that they come in bigger intake ports than the AFRs.
If you want maximum power, I believe maximum flow is more important that velocity. Id order a set of 255s for my 408 today if they were ready to ship.
I know a couple people have been waiting for close to 3 months for their heads. Thats my only hesitation in ordering. Who knows what I'll want to do 3 months from now.

I'm in the market for a set of heads for a new 402 but am having a real difficult time making the choice. The flow numbers just don't seem to tell of much differance between both 225's (AFR's & ETP's). I don't know if its just hype on the part of the new heads or if they in fact do work better. I really wish there were some side to side tests with these heads....
