question about hp gain from bumping up to 3.2 s.s. and adding 1/2 pt compression?

I have a nice running 3.0 with Mod S cams, 9.3:1 C.R., webers and some mild port work. It is pretty healthy.

I am thinking about putting some 98mm p/c and bumping the compression up to about 9.8:1 possibly going to 10.3:1. The heads are twin plugged already, I just need the ignition stuff.

How much H.P. and torque should I hope for by bumping up to a 3.2 S.S. and adding 1/2 or 1 whole point of compression.

T.I.A.
