[Boostisgood]

How much hp or ET gain are a good set of fully ported stock heads w/ bigger valves and good springs worth?

Really?? Did it help that much? I need some top end power, and was thinking about doing the heads. If it helps that much, I may go ahead and do it. Anybody else??

I think 50 hp would be a good guess assuming everything else is good
