Just did a compression test and leak down test this week on my 540 9:1 with shaved heads, 147 to 152 lbs in all cylinders. Leak down showed 7 to 11%, this was a cold engine.

Sweet. Those are good numbers that will only get better with a warm engine. Often a survey customer wants a compression test with the survey. If I can get good numbers like yours cold, then the warmed-up numbers will be even better.
