i don't see the cranking cylinder PSI coming up that far w/o a cam timing change. i suspect the timing set has the cam in the emissions era retarded position and is lowering your Dynamic Compression Ratio. during tear-down, set up the degree wheel and find where the cam is and compare to desired spec. advancing the cam will close the intake earlier and generate more DCR
