Just my opinion, but, if you need to tell them anything, it is NOT to work on my engine as a good shop will have that data onhand and WILL reference it during the course of repair...basically..they will clean the block, inspect for cracks, bore minimum standard oversize..fit new cam bearing, new core plugs, inspect and turn the crank only if needed..undersize bearings are available for standard wear in .001, 002 and .003 to install on a micro-polished cranks that has not been scored. Cleanliness is the key...new chain, timing gears, oil pump...cam specs checked...probably the most important part of this is the piston fit, bore then last few thousands are hone fit for clearance..the valves should get all new exhaust..these get undercut too many times and are usually installed out of length. Guides are more than not a good investment at any time, never but never let a shop say they can knurl to fit..that is BS..short time fix at best..leave this for chevy engines that smoke at 2000 miles anyway..Piston ifit is key, piston lands are to be decoked..odds are these are about banged beyond as it is...new pistons and pins should be fit...anything less is not an rebuild but a refresh...
If the shop has to ask for specs..leave and carry your engine with you.
