compression test question

125-135 psi is NORMAL for a stock 225 /6 motor in very good condition. I got 130 psi +/- on all cylinders with a solid, fresh rebuild with fresh bores, pistons, and moly top rings, the head shaved a bit, and a very mild cam. The compression ratio is just not there for higher numbers in a stockish /6. And yes, the throttle being open vs closed makes about a 5 psi difference on a /6.

Acceptable leak down %? I gotta laugh about this one. 4 cylinder piston aircraft engines are allowed far,far more leakage than is being cited here when cold! Something like 30%!
