Thanks. I’ll finish the heads before I look for pistons. Based on the one 59 cc measurement with the current pistons I’m at 9.45 assuming 60 cc after cleanup, but they are flat and 50 in the hole. With a .039 gasket, plus .050 deck clearance and .035 in the chamber; that’s .124 total. That number seemed horrible and I started looking for a stepped head piston, with greater compression height. Except for the KB232, the others I found increase compression. That’s why I said I went to the compression question.
