On a set of old heads, I could get to [year unknown] large plug is 34.83mm. Small plug is 22.70mm.
May not be "exact", as wiggling gauge & other read outs, vary a few .mm. Also, this is the inside of the seated plug. Not the outer rim. Guess I'd have to pull 1 out of the head to measure the hole. Hopefully that gives you something to work with.

See amc 304 heads freeze plug sizes
Looks like Advance & others, sell full kits, around $6-$7. Also 304 head Forum comes up.
