Thanks man. You have to plug the AVCS holes in the STI cams if you're going to use them in the 2.0 non-AVCS heads. There is a thread floating around somewhere on NASIOC on how to do it; it's pretty straight forward. The only other thing you have to get done is have a machine shop set your valve lash for you as it will have changed.
Nice Hybrid Build!!! Almost exactly the same setup as I have.....although mine isn't done yet lol. So by reading your mods, i guess its fine to use sti cams in the 2.0L heads? Were there any issues?
