Elsewhere, it has been mentioned that 0.035-0.050 is a desireable target for quench, and that the current head gasket offerings are currently at least 0.025” thicker than the originals. Fel-pro publishes its MLS gasket thickness at more than 0.050”, and I just measured one I took off of a rebuilt 223 and got 0.060” with my calipers.
If the head gasket is 0.050-0.060” thick, doesn’t that make it the limit as to what quench can be attained? If so, since it is possible to buy an NOS steel beaded head gasket, is there any objection to using the old technology to maintain quench and compression? Seems like a head gasket that requires sealant wouldn’t be as reliable as the modern stuff...
