superdart,
I think that you have this thread mixed up with the 322 thread as in the 3rd paragragh I use 360 heads.
They will work fine and actually what the engine needs. The 302's would be used if the engine was going to be a Tq. only engine with low RPM's and a 4000 RPM limit. Definitly use the 596's. But due to chamber size cc wise you'll have to check as to what your final compression ratio will be. You may want to cut about .060 off if this hasnt been done yet, and then cut .075 off the intake face so the intake manifold will fit properly.
