checking for cracked head or bad head gasket..

Have you run a straight edge along the intake runners yet? ~~~~

yes i did its not the intake...ive told a million people.. ive used this intake on my last set of heads with no problems...I did a compression check and number 1 cylinder has 150 and number 3 has 180 and number 2 cylinder has 150 and number 4 has 180 so im guessing head gaskets are gone..also that noise i complained about...is happening with no distib in and intake off.. I think it might be air escaping from the head gasket
