Hey cheapskate, buy a new set of 15 dollar plugs and put them in there, the TR6s are the way to go tis why I put them in there. Ive run them on bolton cars with no power loss, so I wouldnt be scared.

You are going to smell some kind of fumes with a 240 duration cam, irrelevant of the air fuel. Obviously its not that rich or the plugs would be sooted up more. Looks more like oil consumption thananything with the greying of the porcelien.
That's what I did, .040 gaskets and a slight decking of the heads puts me at about 11.5:1 with around 8.1:1 DCR I believe, which is a hell of a lot better than the 7.4:1 I was running. I'm about to give you a ring Jeff.
