MLS gaskets are thinner I think it is .025 thick

Check felpro's site also for the requirements to using a MLS gasket, block & head surfaces (for the MLS) have to be prepped better then stock felpro replacement gaskets surfaces.

You can also order different bore diameters in these to increase compression if you need it

The 9966 is a stock replacement and is most likely the same thickness as stock , .051.The Performance gasket 1074 is .039 compressed.
