I think you'll lose 2-3#'s of boost.

Just look at the BD11 kits for the LS1's (5.7L) displacement, they run these kits (same pulley ratios) at 4-5psi andstill have higher C/R as well and still end up w/lower boost #'s. Basically those heads flow really well.

I have a 347 with 8.5 compression, out of the box AFR 185's, Cobra intake with just gasket match work done, and a cheap powerpipe(can't even remember who made it). Its the 9 lbs kit, with the stock pully on the compressor and a 7 inch ASP crank pully I see about 7 1/2 to 8 psi.
