Stupid pre-buy questions

jaywalkker said

Thanks for the tips MVH! Quick question on the JBWeld for pits - what qualifies as a pit? Are we talking any holes or scratches that are BB sized? Smaller like #12 shot sized? Or just "any scrape, pit, gouge, or other deformation that's visible to the eye should receive treatment?"

Thanks for tip.

Dan knows what he's talking about. But in my case the manifold was good, it just had a couple small gouges near one port, and a few pinhead size pits in some others. I figured if I was going to all the trouble of filing down flange surfaces to match, I would make the sealing surfaces perfect. Part of the reason my flanges needed work was that this was a mismatched set -- a 1977 2bbl intake and an unknown exhaust. That probably doesn't apply to you. At any rate, I have no manifold leaks so I'm happy.
