Head gasket sizing

Have you used those .028s at say 190psi cranking pressure, and how long did they survive?

had them on my 360 that ran 11.20’s at 3300+ for the last few years before swapping to my stroker. Cranking pressure wasn't that high, but that's a steel shim gasket, its capable. Rated for up to 12 to 1 compression.
