Exhaust port repair

[baz]

I use high Temp red Loctite.

Is that the 648 ?

I don't post much here anymore, but I'll jump in to say that Comnoz fixed my exhaust threads a long time ago,
working his magic with bronze inserts.
Everything is still tight.
Highly recommended!

Seager engineering in Essex/Suffolk , UK do a vg bronze insert, threaded into head, and some matching exhaust collars to screw in. Just plan ahead, as they are very busy!! They have a facebook page which has lots of great pics of what they do 5 days a week.

I follow Seager on Facebook, and some of the stuff Pat does (saves) is nothing short of miraculous.

Some years ago,someone (I can't remember his name) was advertising in INOA Norton News. He would make stainless steel oversize exhaust nuts. They were 2 inches dia. instead of the standard 1 15/16. They woud stay in place with an allen screw against the port side. Shiny and beatiful made!

Personally I would stick to standard size. Colorado sells the Stainless steel ones which requires a special tool to tighten them. https://coloradonortonworks.net/part-categories/cnw-special-tools.html
I have these on my personal MK111 and really like the look.

I think it was "Schults" (sp) that had made the over size exhaust rings. He also made the one piece rocker shaft covers.
