Default How much HP?

How much more HP will I get if I go with stage II ported and polished heads versus a stock PI swap. I do plan on Stage I cam set for either set-up. But I;m not sure how much more I will gain by going that route?

Let me rephrase this. I'm doing a PI head swap with stage 1 cams! I want to know how much more power will be added if I step up to the Stage 2 Ported and Polished Patriot heads?

that's what he said, with the stage II heads you'll gain 30 more hp, but with those stage I cams, and the stage II cams you'll gain 50 more hp than a stock PI swap (im guessing thats what he meant atleast)

Then it's not really worth it to spend $700 more on Stage 2's for only 20-30hp?

All the bolt-ons with LT's O/R H-pipe and catback. Plus I'm getting a tune and dyno done when I finish!
