stu Posted August 31, 2018 Report Share Posted August 31, 2018 Hello, can anyone quote the thickness of a standard 218 head gasket? Mine seems really thin, like .010" Thanks, Stu Quote Link to comment Share on other sites More sharing options...
vintage6t Posted August 31, 2018 Report Share Posted August 31, 2018 Don't know off hand but I have some NOS gaskets I can measure tomorrow and post back. Quote Link to comment Share on other sites More sharing options...

sser2 Posted August 31, 2018 Report Share Posted August 31, 2018 Should be measured in compressed state after torquing to specs, otherwise meaningless. Quote Link to comment Share on other sites More sharing options...

stu Posted September 1, 2018 Author Report Share Posted September 1, 2018 Thank you Don, that is what I needed to know. Yours appears to be a composite gasket. Mine is a single layer of copper, .012". Quote Link to comment Share on other sites More sharing options...
thebeebe5 Posted September 1, 2018 Report Share Posted September 1, 2018 Cometic will make a gasket to match that one (or nearly...) if you need it. Otherwise, Don has the answer. I’ve measured both old take-off gaskets and new FelPro composite gaskets in the 0.075” range. Have not had a copper shim gasket to measure as of yet. I will say that if your pistons are zero decked (piston tops exactly even with block deck) you’ll want a thicker gasket. Should have about 0.035-0.040” quench for best running. 1 Quote Link to comment Share on other sites More sharing options...
greg g Posted September 1, 2018 Report Share Posted September 1, 2018 The solid copper gasket will not do much compressing when torqued. They are reusable after they have been annealed. The annealing process relaxes the metal restoring its malleability, bringing it back to usefullness. Quote Link to comment Share on other sites More sharing options...
