fire ring diameters of various head gaskets

I have already done that.
I have 3 here in all, 2 peanut and 1 drool tube (which is the original one from the engine that I have)
I don't think that any of them had been touched since they left the factory, and all 3 have a couple of chambers that are jagged around the valves, and I was just trying to smooth out the jagged-ness on one of those, and I was gonna try to equal them all out in the end. The head I'm worried about being into the fire ring is a peanut head, no AIR provisions. And the one I have the most time into.
I started on peanut head#2, it has the hole for the AIR tube in back but no holes in the exhaust ports like pix I have seen of heads that do.i have that one roughed out, haven't hit it yet with the sandpaper rolls to smooth it. I wasn't wanting to go with the drool tube one because going with the peanut head would eliminate 6 leak possibilities. But I might have to. I have gotten into the original seats bad enough on that 1st head that I'm gonna have no choice but to put it together with OS valves which I planned on from the start. I'm planning on having exhaust seats put in regardless.
I am gonna take both of them in for evaluation once my OS valves get here and see what happens.
Actually the grinding doesn't look square to the deck, and it's getting a shave no matter what if it is savable. I'm thinking that with the shave, I might lose the ground out part that overhangs the fire ring. I'm hoping so anyway.
I'm gonna pull the drool tube head apart and clean it up under the valves at least, just in case I have to go with that one.
