Stan. I can’t see having only 40 psi of cylinder pressure can take place no matter how far out the Cam phasing might be.
I also don’t think this fellow right now would know how to check Cam phasing .
If that cam and new lifters went flat then there’s likely a good amount of metal grit in the motor and that’s not good for rings , pistons , cylinder walls, oil pump and Bearings.
Since you don’t know what cam got put in the motor its Going to need to come out to
1) determine its condition.
2) check how much lift it has so you then knowe what needs to be checked out and done to the valvetrain.
The machine shop needs to crack test the heads, not pressure test them.
