9.5-10:1 compression
Bowl port the heads
Hyd cam in the 225* @.050" range (like a comp cams XE268H) or a solid in the 235* @.050" range

Eddy Rpm or Rpm air gap, I cant see there being any difference in power between the 2, A LD340 would work well also.

Holley 750 carb either a 3310 vac secondary or a 4150 double pumper.

Good machine work is the most important part when trying to build good power with mild parts.
