[Fot] Head gasket

[Bob Kramer]

I think that's why some of us still use a sealant. With the fire ring
thickness on this gasket I can't see a downside to a coppercoat spray, or
better yet Hylomar spray. That stuff is hard to find. I'm also a big fan of
using Gasgacinch which can be applied manually.

I gave up on using these gaskets for the race engine. The eyebrow cut in
the liners and the shape of the combustion chamber on the milled head did
not leave much surface area for the fire ring to seal. I'm back to shim
steel head gaskets.
