ET performance, now Induction Performance, as Cary (guy that did all the design work and porting@ ET broke off and took the castings with him, to make the story short.
11 degree heads, and you don't need any special rockers or any of that to get the geometry right. I've been running a set for 3 years with stock rockers, and not a single problem.

Yes you will and they work absolutely perfect, I've been using them for 3 years, no problems.
Those rocker stands are WAY cheaper then buying shitty aftermarket roller rockers that like to have problems, fail, weigh a good bit more then stock and cause valve control issues.
If you're staying hydraulic roller, the stock rocker arms are all you need, hell do the harland sharp upgrade to them if you want, and that's all you need.

if it is a 346ci LS1 go with the 215cc TFS heads
if it is 402ci-408ci go with the 225cc TFS heads
if it is 427ci-441ci LS7 go with the 235cc TFS heads
if it is 454ci LSX or more go with the 245cc TFS heads.

i will go with 1.7 Yella Terra non-adjustable roller rockers for my touched up 215cc LS1 TFS heads. don't forget to get the proper lengthed pushrods for the use with the TFS heads becuase they have 13.5* valve angle versus 15* valve angle for the stock heads. mine were 7.800" pushrods with 0.005" mill for the TFS heads.

I wish that I could say the same - 3000 miles and porosity in the exhaust port via the water jacket. Sent back to ET who couldn't replicate the problem with a pressure test, thus, they've been thrown into the too hard basket.
Happy to take the $$$, not happy to fix a casting fault of their own, or replace/refund.If anyone wants a set of complete 62cc low-mile ET215s that leak coolant from one exhaust port, then PM me.....
Sorry to take the thread OT - for mine, given what I've seen, it'd be AFRs, as they work with oem rockers, etc....
Cheers,
Macca

Macca have you contacted Cary about the problem since he left ET and has taken over the product line? I would, and see what you can do.
Fwiw that's the first instance of that I have ever heard of, mine's been chugging along for 3 years now with no issues and had been a solid performer to say the least.

Yes, done and done mate - still no joy. Fraser at speedinc - the vendor - is trying to get the problem sorted out. I certainly do not want to chuck $US2.5 k away - that is for sure.
