@Heywodja delivered the engine to my dad earlier today. I’ll have pops find the date of casting. It should be up to 93 or 94 that they had the block drilled for head oiling, right?

Good question. I think they stopped drilling them in 93-94ish. When he takes the heads off, have him snap a photo of the deck surface. I'm sure you already know, but this is the hole you're looking for:
