so i picked up a 350 four bolt main today and i'm trying to decide which heads to use; the heads that were bolted to the block or the ones i have in the garage.

the engine block casting # - 14010207

option 1: a pair of "camel hump" w/ 62 cc chamber, casting# 3782461

option 2: a pair of 76 cc chambers off a '75 'vette, casting# 333882

how would the changes in chamber size affect the engine?
