I had these because I was going to build a high boost 408 stroker, but instead went with a milder all motor setup and thought these would be kind of an overkill. These are some of the best head gaskets you can get! I paid about $225 for these.
These are 4.060" x .050


I have included some info about these at the bottom of the post.

I will let them go for $125 shipped

SCE ICS Titan copper self-sealing head gaskets--SCE's ultimate head gasket.
With their built-in combustion, oil, and coolant seals, patented SCE ICS Titan copper self-sealing head gaskets don't need any sealants. That means you get user-friendly installation combined with reliable fluid sealing, plus the unbeatable strength of solid-copper gaskets. The fluid seals are bonded to both sides of the gasket and cleverly offset to allow the annealed copper of the gaskets to deform around them for a better seal, especially in the O-ring combustion-seal area. SCE ICS Titan copper self-sealing head gaskets are the results of an 8-year development period and are currently used in competition on midgets, fuel cars, boats, and sprint cars, as well as on blown, turbocharged, and nitrous-fed street rides.

I just blew mine and am thinking about these.
