It's true, most small block Chevy engines have no markings from the factory. SOMETIMES, there's a number stamped into the cap on the bolt "flat".

If they are truly the original caps from that block, it takes about 15 minutes for a machinist to "sort it out". Not complicated, but helpful to have the correct measuring tools, in this case, a bore gage, set to the housing bore size. If all the visual indicators that Bob mentions are "there", making sure everything is "round and straight" will take care of it.
