119cc heads with H112CP-100 pistons will produce 10.2:1 static compression ratio with a 9.785" stack and 0.040" gasket. Align hone the main saddles and take a light cut on each deck to you know that each corner of the block is the same distance from the centerline of the main bearing bore. The combination I'm showing here assumes a 9.795" to 9.800" stock block deck height.

I don't think you will be happy with warmed-over production heads. They're just junk compared to some of the aftermarket heads being currently produced. $779 per head (assembled) seems to me like a heck of a price for a BBC head that makes this much power. My very best advice would be to put the project on hold until you have the money to buy the good parts. Don't blow what budget you have presently and be unhappy with a turd motor.
