Line boring
These caps are old but new. I don't plan on milling these caps to fit this junk block just was trail fitting them since I plan to put them on the block I'm going to use. Yes I agree with you on a machine shop putting them on but I want to learn and again yes it will be line bored and honed with studs after the block filler has a few months to cure. I used the OEM bolts to locate the caps in to place to drill the outer holes. Also I've been sick so the sneezing has already occurred.
