Checking oil pan-to-block clearance

Checking oil pan-to-block clearance
The last step to assembling my short-block. I got a hold of the GM tools to install the front and rear covers. That worked out great. Now I'm concerned about getting the correct clearance between the oil pan and block rear face. The factory book specifies it should not be more than 0.010-inch. I guess that's to make sure the bellhousing mates evenly and doesn't stress the pan/gasket surface. So I'm supposed to use a straightedge - I guess against the machined surfaces at the bolt areas on the pan and the rear of the block. It seems like it could get tricky to accurately get between 0 and 0.010. Anyone have any tips?
