Given I will likely only use them once, I'm hesitant to buy a bore gauge and micrometer capable of measuring down to this degree, as they appear to be extremely expensive. Not sure if I'm better off bringing them to a machine shop.
Maybe a stupid question but does your average machine shop typically measure this precisely? I'm sending my heads to Anchor Atlantic and haven't looked yet for a local shop to do the inspection, polishing the crank, conrods, etc.

You don’t have to buy the most expensive tools to take these measurements. You can buy a set of old school bore gauges for next to nothing. You can buy a cheap dial bore gauge throw out the dial indicator and put in a halfway decent one. China has done a good job of ripping off all the quality instruments, will they last? Probably not but good enough for what you need. Or buy used on eBay
