Opinions needed: How bad is this exhaust manifold face?

[joeydurango]

Pulled the driver's side exhaust manifold (rams horn old school style) off today to try and fix an annoying leak/tick. I know these were mounted factory directly to the heads, no gasket involved. My truck had gaskets, the "slide-in" kind, but they didn't look to be in great condition. I cleaned up the faces a little with a broad, flat file, but didn't want to go nuts of course. I see pitting, but I don't have any reference to know how bad or normal that is.

Trying to decide if I need to put new gaskets in, or if I can simply use a bead of copper/silicone high-temp exhaust gasket maker to account for the pitting.

So, the questions: How bad are these faces (particularly the last photo)? And what's your opinion on the probable success of copper/silicone gasket maker and nothing else before reinstall?

Thanks!
