I'm looking at an update to rebuild of my motor. Ran an compression test {205 to 198 psi} Motor has low oil useage. 35 - 40 psi oil pressure when at operating temp. It appears that the motor has been rebuilt. I removed the pan, the caps were number stamped. I have headers as my only upgrade. I would like to check the specification of the cam, crank and bearings. Possibly take apart one rod bearing and rear main. Far as the cylinder heads go I want to prep them as Duke as recommended. Looking for advice.
