340 Rod questions

To somewhat close the loop on this topic.... I picked up my block from the machine shop this week. I had them run their rigid adjustable hone through the block and remove the slight ridge at the top of the cylinder and just rough up the rest of the cylinder enough for new rings to seat. You can still see the light vertical scratches that were in a couple of the cylinders so they didn't open the bore much if any. Block got cleaned out, new freeze plugs, and new oil pump drive bushing as well as cam bearings. Now need to order main bearings, rod bearings, and a full ring kit. He thought the crank, pistons, and rods looked fine. I was going to do an overbore with pistons and rods, but the body work I was having done turned south when we found additional hidden accident damage which required an extra $2000 in parts and labor, so it will have to get by with the original pistons. Not optimal but I'm sure this has been done many times and should get me by until the rest of the body work is completed and it is ready for the stroker, or whatever the next level will be. Still would like to figure out the variation I have in height above deck on the pistons, but I'm not going to obsess about it and I'll just pick a head gasket thickness that will keep me safe.
