I have a poly instead of a wedge but I'm sure the problem exists in all of these. There is a lot of heat and I think it dries out the sealer. I did use the high temp good stuff too. I had the rear 'bolt' (in my case) spring a leak shortly after break in. Then after some racing a few years later the right front bolt starting spitting AF. I could just barely see the steam but heard it sizzle when it hit the headers. There's no way I'd remove those headers unless it was absolutely necessary. Just ask Paul Lenneman :-) So what I did was drain down the coolant and remove the bolt. clean it up and reseal it. I got pretty aggressive with the rear one because it happened again so on that one I gave it a dose of the black aviation sealer. That may bite me when I do have to remove it but for now it doesn't leak.

Before you add header, put a small bead around the stud again, and install header. I have a stud or two that are a real pain in the ass sometimes. Once it is sealed, it should be fine. Pull the studs and install new if needed. Good luck.

Hmmmmm.What do we have here?Thanks, Donny, 64 BelvedereRich Kinsley '64 Dodge Polara 4dr 318poly w/goodies http://1962to1965mopar.ornocar.org/ml-kinsley64polara.html ---- Please address private mail -- mail of interest to only one person -- directly to that person.
