Head ? Compression ?

Mods to motor are TSP 228R-112, LS6 intake, LT headers, P&P TB, and UD pulley!!!! It has the stock 853's and some 28# injectors also. I want around a 11:1 comp and i have some 243's sitting in a box, what setup would you do to get that goal and would these gain me 25rwhp since i have a nice size cam ????

Mill the nead some and run a .040 gasket. The head swap and compression bump might get you in the 20HP gain area give or take some.

You'll get better quench (= less detonation) if you leave the heads unmilled and run a thinner gasket.
