What is the best stuff to use?
Is there anything out there that will survive the heat in the exhaust port?
Also, where can you get the stuff that you are recommending?

This is a two pack epoxy putty, used by plumbers to repair or seal, cast iron pipes. You mix the 2 parts underwater, or at least fully wet your hands first, then it will wash off.
It sticks to metals like the proverbial sh*t to a blanket, and is very tough and as good to temperature as you can afford to buy. Also, being avaliable from builders supply houses, it is relativly cheap.
In Australia, it is called "Charmac Pipe Jointing Compound"

I too have used JB Weld in intake ports, even in "air cooled" heads with good results, contact them for details. As for the exhaust side never even thourgt to try, the heat is too high.

No "epoxy" will survive in an exhaust port. Welding would be your best option there. A very specific process though.

I have always used welding in the exhaust port. The problem is that the welder cannot get into the port as far as I need.

I've used the aluminium filled version on the inlet ports of aluminium cylinder heads and they've quite happily lasted for 500 hrs dyno running. No chance that you'll find anything that will live at 900°C exhaust port temps though.

Call these folks. You might get lucky with a ceramic/putty.
