CBGT is not IME an easy measurement to get accurately. I usually measure the thickness on a new gasket, smear a light coat of grease on it, then install it, and torque the cylinder to spec, wait an hour, then remove the cylinder and measure immediately again. If I let it sit on the bench for more than a few minutes and measure again, it has changed thickness back toward the original measurement.

I am wondering if there is a limit as to how far the gasket will compress over time. OBTW, these are factory or after market standard gaskets, not reinforced PTFE gaskets.
