welcome to the forums...
bolt on a set of AFR 165 heads.... apparently, they netted nearly 100 hp on a basically stock motor.... now granted, that's not peak horsepwer gain, but on some parts of the power curve, it was a direct 95 hp difference.... the peak to peak difference is more like 65 I think, but still a huge power gain
