I am rebuilding my AD3 152 Perkins in my 1969 MF135 and I'm at the stage of installing the head gasket. The Jensales manual I bought states "lightly coat both sides of the new cylinder head gasket with an aviation grade sealing compound (non-hardening). I have the copper gasket which is the same as the one I removed before the rebuild, does this copper head gasket need a sealing compound? I have heard of a spray called CopperCoat, I also have a Permatex Anaerobic Flange sealant that I used for the oil pan gasket but I'm not sure if I should use that.
Also do I need to retorque the head after a certain number of hours running the rebuild?
Thanks, Don
