Wouldn’t his receipts show the type of head that they used to rebuild the block?

Unfortunately…the receipts don’t go into a lot of detail. Like spark plug numbers, gasket numbers, etc.

Usually guys used a hotter plug if the engine was getting tired and burning some oil. The hotter range kept the oil residue burned off the plug so it would not misfire. A band-aid solution to an eventual rebuild.
