I'm trying to determine how I will get these measured, given the precision required.

The spec in the service manual for the cylinders is 95.014-95.021mm. The pistons are 94.979-94.989mm. Crank journals are similarly precise. .001mm is .00004" That's 40 millionths! I would think changes in ambient air temps would throw off these measurements.

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.
