I need to make a template or gasket of the exhaust ports so GP Headers can duplicate the
same shape in the header flange. I ordered some gaskets that were small enough when you
consider the L X W, but the corners in the head caught me out with their large radius. The
ports in hot rod lingo are called "D" shaped ports (See 3rd photo below).
I used these to locate the exhaust port bolt holes.
Today I went to our local Metal Supermarket that sells in small quantities, cut to your
specs. For what I wanted, 1/8" x 2" x 60" C110 Copper, it would be $150 since it would
have to be shipped in from Canada. But they did have some 0.032" x 2" x 54" that Brian
would sell to me for $20, done deal, I bought it. I really didn't have much choice. I really
needed to provide GP with a template soon, now I could have done something from
plastic and made the gasket later, but I didn't want to duplicate my work.
So this is what I made this afternoon after getting back to my garage.
