I plan on patching up some small leaks in my headers and was wondering what you all think works best...i plan on cleaning off the areas first and then using some high temp sealant of some sort or perhaps some of that liquid weld product. any ideas?

I just spent some serious time welding them up this weekend. I have TRI-Ys and they had some back cracks at a couple of the welds. I think that patching them up with something else won't last as long as welding. check out J-B weld. I don't know if the stuff is good for high temps.

Also, I plan on bead blasting the headers, h-pipe, Y-adapters (so I can run open exhaust at racing events - hehehe), and adapter pipes and painting them with POR-20 (www.por15.com).

Where are the leaks....??

If they're anywhere near the ports, epoxy-based products likely won't hold up...too hot...
Otherwise, HVAC repair putty or most any of Devcon's plastic steel derivitive epoxies will likely work....

Personally, I prefer welding or brazing as a permanent repair...
