Small block combo suggestions

BTW, for 10.5 SCR, the head chambers would have to be around 65 cc's (NHRA minimums) with the .028" head gasket, or around 60-61 cc's with a .048" head gasket.

Or maybe the block was decked down a fair amount. Were the KB107's truly flush to the deck? With a stock deck they would be about .012" in the hole.
