If you have already checked the if wires and firing order, is be concerned about that compression #. That's low. What happened that you needed to replace the exhaust valves? Timing belt snap?

Burnt exhaust valve was the reason of replacement all the rest were fine did a leak test with diesel when head was off and all the other valves were good car doesn't smoke either
