There is a bit of clearance between the side of the cap and block, but the block casting was cleaned up also.
With the oil pan gasket, you can't see the nuts bolting the girdle to the block. The girdle holes for the oil pan studs are counter-bored so the nuts are below the oil pan gasket.
Because the oil pan rail and caps are milled flat, the girdle is right on top of the caps, and the caps bolted to the girdle on the outer wedge part of the caps (along with the normal main cap studs.)

After doing all the mods to the stock block, the costs started getting up there (around $1,600 for the caps, girdle, and machine work), but still way less than an aftermarket block which are around $5,000 these days.
