HEI Dizzy
Stock Pistons
Compression - approx. 10.0:1 to 10.5:1
Summit 1.5:1 Full Roller Rockers

Stock numbers were 260HP and 304TQ and compression was 8.5:1 with 76cc Mexico heads

With upgrade - maybe 360HP and 350TQ at 5,000 RPMs???
I'd use those heads only if I were up against a wall with my budget.
You cannot intelligently choose a cam until you know the static compression ratio. 10.0 to 10.5 is lame and is not the static compression ratio. Measure all your components and figure the exact static compression ratio so that you can intelligently choose the intake valve closing point on the camshaft to make max power without detonation on pump gas.
Stock pistons. Pour the dish with a burette and colored alcohol. Drug store rubbing alcohol works fine, just add a few drops of food coloring.
You should probably pick up a couple of books by David Vizard, like these....
