i understand that if the machining is correct it doesnt need it. which is all well and good but ive never heard of anything it hurts. but ive also heard it helps with heat transfer.
any reason you guys know of NOT to coat a head gasket before install?
I cant see the thin layer of copper spray doing that much for heat dispertion on a composite/paper or graphite gasket. Just more to clean up when you have to pull the head. Just make sure everything is clean and dry before install.
