Rebuild in progress - can't turn crank? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

The #2 cap and #6 cap, when torqued to spec (65 ft-lbs), cause me to not be able to turn the crank by hand. If I loosen these two, with everything else still torqued, it turns quite easily.

I plasti-gauged these two. As best I can tell, they are in spec, at 0.00125 (roughly halfway between .0015 and .001)

I guess this indicates that I need to have the shop check and possibly align-hone the block? Is there something else that could be going on?
