Gary, I have set stubborn, disc type, expansion plugs using JB weld epoxy as a sealant. Worked great, and I would use a brass plug for maximum life.

I finished " Gretie" last fall (aug) and seem to be blowing freeze plugs in the passenger side head behind the exhaust manifold. I put in the 3rd one last week with less then 2000 miles since total rebuild. Engine man says this is the nature of the beast. Any helpful hints?? Gretie is my 61 300 G convertable that I have asked previously. I am afraid to get out of town until I cure this. I also checked the thermostat and is ok at 180 degrees, radiator cap is new and at 7 lbs. Do you have any thoughts or help.
