Re: Steel head gaskets
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.

Re: Steel head gaskets
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.

Re: Steel head gaskets
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. |
