I believe you can use the avcs heads without running the avcs system. They can be blocked off at the oil lines IIRC. I'd say later model sti heads would be suitable. I remember using v6 sti heads on the wagon way back when. They were bucket over shim which didn't seem to be consistent at high rpm i.e. 9k+ GD's have the single shimmed bucket, less moving parts in the heads is always a better option.

So whats the plan Joey?
