I"m concerned that this is why head 'gaskets' are blowing out with this
Alcohol gasoline we have now. New cars likely have something that handles
dual fuels but not older cars and trucks.

I've used Permatex IIb non hardening, for auto gasket applications. Should

Auto stores stock a variety of (usually Permatex brand) sealants
in RTV silicone, including a variety of removable sealants.
If you ever replace/repair threaded fittings, the nonremovable
ones are not recommended.
