fire ring diameters of various head gaskets

Yeah the Aussie head gaskets are up around 3.6". Pretty big. I could use one right now that's thicker than .040.

yeah me too, but I wouldnt want one any thicker than what a Print O seal one would be..... I found a ROL brand one on Feebay for a better than reasonable price, that (by the pix in the Ebay ad) looks to have less space between cylinder bores though pix can be decieving I know... but thinner between the fire rings means bigger diameter fire rings...
What ever happened to ROL anyway? They came on teh scene out of nowhere, were around for a while then poof... gone.
