Like i said in my first post the h22a head flows very good. You wont benifet from any head work unless you are pushing over 350whp.(boosted) You still can use all th have the stock parts and be just fine. If you he has the money why not do it?
As in the turbos since when could you boost the hell out of a stock h22a, Ive always been told to stay under 9psi. Thats what i have always done and suggested to ppl to do. Im not trying to sound harshin any of this btw.
Ive been told by plenty of ppl that the rods are only good up to 350whp. If thats not true im kinda happy about that then.

What are you pushing hp wise?
