There should be a pretty good possibility

with that giving you a 11.xx compression and if the cam is on a 112 i would think more along the lines of 425-430, but with the 90/90 setup also, then yes. Thats with a good tune as well. If they're the older heads, spend the money now and have them looked over and make sure none of the parts are loose or too big/small for the heads..ie valve guides, seals just extra insurance.

I hit 450 (sae) without the FAST so I will say you can hit the number... it is going to depend on the tuning.

When are you doing this???

true, but your running afr's and he has patriot heads...from all the talk on the boards, there's a big difference between the two.
