Block work

First Thanks for the response.
Rings are all in correct, I assembled the motor, it has Manley stainless steel valves. Block was done at a very reputable shop. 95 lbs is what I have researched to be the correct compression reading with 114 lobe separation.The bore is stock 4.25, original forged aluminum pistons 8.75 compression. Sealed power E233K Moly rings. Harland sharp stud girdle. I took it to the strip and it ran bad too lean, I broke the #7 exhaust valve. I replaced the spring and I don't have a leak down tester but left the compression tester on each cylinder for at least 1/2 hour no loss of pressure.
Thanks For the help.
