You know, these Mr Gasket gaskets don't line up well at all with the ports. Their port openinga are too large. There is very little coverage at all at the Tops of the ports.

When talking "no gasket", is it generally agreed that I should use a "a little" copper RTV applied to the manifold prior to bolting up?

and I am assuming that Headpipe to manifold gasket(s) are required. I don't go "no gasket here, do I?
