bostonkevino Visitor	Hi, New guy on the block but wanted to chime in - I've heard several people say the 'silver paint' method has worked well for them. Google it if not familiar. Just my .02 Thx, -kjo Check this box to be notified of replies to this topic. Note: BBcode and smileys are still usable.

Did a little research and found this article in a newsletter from the wayback machine.

I hope it is helpful. I also seem to remember a tech tip in the Norton Digest which covers a number of esoteric topic and unknown facts. I will tell you that Dave is one of the top Norton knowledge base people in the world.

I have two new old head gaskets for an 850 which are of the flame ring variety. They look a little shiny when looking at the composite so not sure whether they are the reusable type. I need one for my 74 restoration and will be very careful when I torque the head. In addition, I will re-torque the head after about a month of use. In addition, make sure your two mating surfaces are true.

This thread really should be in the tech forum. OP can request a move if desired.
One of the problem spots is not cleaning the surfaces adequately on one or both the head and barrels. On the head. the jam nut method of installing the studs leaves a small aluminum bump next to the 3 studs.
Every head I work on, I pull the studs and eliminate the bump that may prevents the head from seating as flat as it should. Then I Loctite 242 or 290 the studs in... finger tight. No aluminum deformation

On the shiny flame-rings, I have contemplated using paint stripper to remove the thermoset stuff. I may try it next build.
