Get yourself an old Motors repair manual(flea market,eBay,reprints) this will help with the procedure. You don’t say what part of the country you’re from but you will need a machine shop to bore the block. Depending upon the wear of the cylinders you need to bore to the next available size. We have a couple of vendors on the barn who could help with parts.
Third Gen auto and VanPelts are some that come to mind.
