Hi all...I'm assembling my hybrid new IAG short block and reconditioned heads. When the heads were on my workbench, I could easily turn the camshafts by hand with the caps torqued to spec. Now that the heads are on the block and torqued to spec, I can no longer turn the cams by hand. I can, however turn them with a wrench applied at the cam flats but there is a good bit of drag on both the intake and exhaust sides. Is there a specification somewhere on how much static drag is acceptable?
