Re: slow cranking '51 300

I gapped all the rings (including the oil rings) to at least .015 at the bottom of the cylinders. I only had to replace the bearings on #8 (it was about .001 oversize via use of platicgauge). i'll pull the pan again, and check everything again, maybe I should put the old bearings on #8 and give it a shot. I don't understand how the engine cranked at a decent speed with the head off, and cranks very slow with the head on. Is there any way to check how hard it should be to turn the engine by hand before I put the head on for the third time?
Thanks in advance
