Yep, everything checks as a 216, which I thought it was. The spark plug size threw me. Someone must have enlarged it or a later head? I'll check that out too.
The plugs in it are old AC 46 which don't appear to have been made for some time. I've read that AC Delco R45 and R45s are what some are using now. Any other sizes/types?
