Specifically, which silicone product is best for holding up to the heat and making a good seal?

Hello,
I use either the red or gold High Temp (Permatex for me). Like Alex pointed out works best on flat (no ground down weld bead) surfaces.

We use those that Mark mentioned and the orange  (I love oranges you know)high heat Permatex products exclusivly. Never ever had a header leak using the high heat silicone with flat flanges.  ------------------

I'm familiar with the red and gold (ultra copper?) high temp stuff. Where do you get the high-temp tropical orange product?

What's the heat range on the orange high temp silicone? can I use it on my exhaust manifolds to heads without gaskets?

It is rated at 1500+ degrees. Works especially well holding stuff in tail pipes. ------------------
