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.

Sorry for the delay. I'm not on here much and I don't get notices. The number I have is Loctite 272. high strength, high temperature. 50ml part # 27240

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!
