Thanks again Curt, your right about the bores in the torque plate. They typically are larger than the bore by about .100-.125 of an inch to allow the bar and honing stones to pass through without contacting the plate. You could probably use a head gasket as a reference and make the bores slightly smaller than the bores in the gasket. Most times an old gasket is also used to torque the plate to the block when boring and honing as well. The thickness of the plate is generally in the 2-1/2"-3" range, and the materials are billet steel but not heat treated, and BHJ also has some that are cast iron. They also offer an aluminum plate to simulate engines that have and are using aluminum heads. Hope that helps, thanks again for the specs! Scott
ps. So that we are on the same page, the bore centerlines are going to be Y-2.050, same as the #2 bolt....
