Gotten bit by them already. No thanx. I installed them when they first came out. After a while, I had to take the heads out. The left head was fine. The right head was not. Valves wobbled in the guides and wiped out the spring which caused the valve to float and hit the piston. I might be willing to go with a bare set where I put my stuff on it. Personally, I'd go with the AFR and did.

Thanks man, good info.

I just realized that they will lower compression due to the larger combustion chamber.
What's up with that? SC applications only?

FWIW, I installed a set on my 96 LT1 A4 in the fall of 06 and haven't had any problems with them to date...











FYI... Cylinder head flow numbers

Designed for SC, Turbo, or a stroker. If you use a stroker it will raise the compression back up, then if you get dome pistons it will raise your compression
