Okay,
So here's an interesting one someone might be able to comment on. I am in the process of wanting to rebuild my engine with a local builder. So far I have talked to a few. Pontiac Engineering is basically gone, talked to Bruce Fulper but very bad feedback but today I was at our local high performance swap meet and saw a builder there called HPS. Asked about doing my engine. Talked about head work and asked him about porting and how much flow I could get. He mentioned to me that I wouldn't want to port them 2 much (not sure if he sad the intake or the exhaust but it was one or the other) or you could actually lose power. can anyone comment on it?
