Not quite sure how you come up with that. These pistons http://www.summitracing.com/parts/TRW-L2491NF30/ with a 72 cc head, and an 028 head gasket comes in around 9.5:1 according to my calcs. PHV is 3.40cc's so technically i guess its not a flat top, although the piston is "flat" on top. Scratching my head on why the compression distance is so small though.
