yet another exhaust manifold query

Instead of grinding the head I made a spacer out of a piece of 1/4 x 3" strap, for my 302 heads. It turned out a whole lot better than I thought it would too. I used the ports as a template and cut holes and made it the shape of the gasket. You cant tell its there unless your really looking for it. Before doing this I learned the hard way about the fit on the 302 heads, needless to say I have an extra broken manifold.
