Is milling the only answer?

Hi All, see this pic for a fine example of TVR's best. This is one of the exhaust manifold ports, looks like the original casting was low in the bottom half of the picture on this port, so TVR added some weld and milled it back. Only they did not weld over the whole low part and the gasket was blowing. FYI the head side is good.


Suggestions on the best gasket sealant to use in this location appreciated as an alternative to getting the faces milled.

Opinions on this plug also appreciated. Is this running too rich? Or about right. Standard 4.0 was doing 187 at the wheels corrected. So not too bad I guess.

It just had paper ones before. The ones I have are a bit more robust, and composite, but would be happier with some sort of paste too.

That's the problem, the head is flat, but the manifold is not. See picture.
