Mine was 12.5 to 1, cranking pressure was 230-240 lbs.

I'm going with new custom Arias pistons with my high riser 72cc heads and shooting for 9.5-.8 compression this time (street use).

You DID hold the throttle wide open while doing the cranking compression test I hope? If not the engine will "starve" for air and you'll get a low reading.
