Whatcha reckon the port temp will be? I´m thinking of using a copper high temp silicone for exhaust gasket as a standard 38mm gasket is covering some of the porting. I know, a tad anal but a quick fix...

Got to be a good couple of hundred degrees, you need an infa red temp reader

You can expect up to 1200 degrees F Kw (around 650 C).

So i guess me should find someone who can make copper rings them....

Have you looked for washers, either alloy or copper in the size you require?

That`s 38.1 mm, you would have to file the rest out.

I know I use to always seal the triumph headers on the bonnie with plumbers roof and gutter silicone sealant.
Never had a problem and one less copper for me to worry about ,the only problem with the heat was when them coppers did give me a hard time but they could never catch me anyhow
