Don, I have built countless flatheads and have applied copper-coat to each and every head gasket.
I would not consider anything else. It works - period.

Same here on v8s and 4cyl Ts

I always just use a good grease on all gaskets. Never had a problem with seal and they are easy to remove. My 2¢. Tell me why I'm wrong.

Coctacted fel pro tech line! Also ,,,guy said copper coat or there was another sealer I forgot,!,,

Best gaskets also recommends copper coat. But with cast iron heads I prefer copper head gaskets as they are more malleable, and can sometimes be reused. Steel are fine also and probably less expensive.

If everything is clean and FLAT it does not matter whether you use a sealant or what type sealant. I have used aluminum paint, copper coat, and nothing without problems when iron heads are installed.


Torque nuts in several even increments and DO NOT over-torque. Go through at least 3 hot-cold engine retorque cycles and drive forever.
