Cold compression test

What are you thinking about my compression test?! 1800 miles after rebuilt.
Do theses numbers could be better after more miles or they are what they’re supposed to be ?1 : 1522 : 1613 : 163 4 : 152

1 : 152
2 : 161
3 : 163
4 : 152

Cold, they are good. Difference between hot and cold readings is about 15-20 psi extra.

Book readings from the fsm for a 650 is 165-185psi hot. A 750 E is around 140psi hot (I think).
