As somebody on FSP suggested, I centered it as best as possible and then torqued it down. The car seems to be running fine - idles a lot smoother than before - but I haven't driven it yet due to a bad valve cover leak (should have looked at those flanges before painting/assem.!) and a leak at the manifold to pipe. I'm hoping I don't need a new head pipe - they had to mill quite a bit off the exh. manifold surface so it may have moved the manifold over too much to seal to the pipe.

Hopefully, I'll have be able to drive it by the jingle bell cruise in early December
