About a year ago I bought a car with a 1979 4 bolt main GM 350 bored 30 over. I would like to get between 350 and 400 usable HP and decent TQ. I am looking at max HP around 5500-6000 RPM if possible. My cam specs are.

I am running an edelbrock RPM manifold and 600cfrm carb with an MSD distributor and coil. The manifold and carb I can change out but I would like to keep the cam. The valve train is rebuilt 882 heads with comp cams roller rockers 1.5 and 600 lift springs. I have a chance on a set of GM phase 2 bowtie heads for a good price they are 184cc 2.02/1.60 65cc chambers do you think they will be what I am looking for?
