fresh machined surface block and heads, 241 dodge hemi, install the head gasket dry or spray it with something
Grease. If the surfaces are properly prepared and the gaskets are of good quality, a coat of regular grease (though really not needed) will make removal much easier and may even allow the gasket to be re-used. The purpose of the gasket is to seal the surfaces; sealants shouldn't be necessary.
It looks to be made of Grafoil which i believe you only install dry. The graphite bonds well to the machined surface and generally can not be reused because it bonds so well.
I’ve done them both with spray copper seal and right out of the package on regular street engines and never had a problem. I would lean towards using the sealer for sure if the surfaces were in doubt but yours have been resurfaced.
sr>>So dry? >> tubman>>> Grease. >>>a coat of regular grease>>> Yes. Grease! Regular wheel bearing grease. I still use Sears & QuakerState green grease in gallon cans purchased a long time ago, not too far away from here. Smeared on all 4 surfaces with my fingers. Works well on just about everything except exhaust mainifolds..
