fire ring diameters of various head gaskets

well I found a deal that was too good to pass up, a freshly redone (30-ish years ago) peanut head, all new valves, still sticky with what I think is cosmoline, doesn't look as if it was ever shaved (if so it was minimal) a guy had in his basement all wrapped in plastic. looks like it came fresh from the machine shop yesterday.
I'd like to pull a couple of valves to see what was done.... valves don't look sunk.... so that gives me 3 /6 heads that don't have chambers that extend into the fire ring.
