Does anyone have the stage 2 heads and camshaft from powerheads.com? They claim you can gain like 100hp or something like that with the stage 2 kit but since I already have upgraded my intake manifold I see no need to get the full kit but I do want to gain some power. What sort of increases might I expect? I just figure that 100hp for 2000 grand isn't too bad. And it's always there where as nitrous isn't so yeah I liked the sound of it but still need more info if anybody has it.
