Should I use a sealant such as Permatex Spray-A-Gasket Copper Hi-Temp or K&W Copper Coat Gasket Compound, on a new copper head gasket during assembly. All surfaces, engine and head have been milled flat. Just want to install the head the proper way. Your advice would be appreciated. Thanks
I use the copper spray on the gasket, and not had a (knock on wood) problem yet.
Should you apply the sealant to the engine and head surfaces or just both sides of the gasket? Thanks
Copper both sides of gasket
