fire ring diameters of various head gaskets

I know that over the years people have gone wild with modifying these engines, with bore jobs of 0.060 and more being common.
I am not planning a very "wild" build for mine, just a little more grunt and motivation for a truck. but I am experimenting with head porting and I "think" I might have gone just a little too far in grinding out one of my chambers to where the HG that I have on hand (older Fel Pro's before "Print-O-seal" came along) I bought a pile of /6 parts from another member here, and within that pile was 7-8 of these head gaskets. I haven't done em all yet, (work in progress) but I have played around with the chamber around the valves to "unshroud" them a bit, mostly on cyl #1.... and the new edge of the chamber cuts into the fire ring on this model HG a bit.... oops.... I ground it out a bit here because I want to run the OS valves in it.
does anyone have measurements of fire ring diameter on different brands of head gaskets? Print-o-seal? ROL? Detroit? Victor Reinz? or anyone else that makes head gaskets for a slant? I'm done with this head for now until I find out what I can do for a HG, I hope I didn't turn the time spent on this head into "practice"..... I do have 2 more that I can port out, I just stripped out one of them today, gonna spend much of tomorrow in the garage making metal dust..... (I want to clean up this 2nd head a bit anyways, as if I have not wrecked the 1st head, my son also has a slant powered pickup, that I want to do up a head for)
