I think Nortons have oversized valve guides available. They are not to difficult to make, i have done a few for my Norton Friends. Over sized oversize

Russell Motors used to supply them and maybe they still can. Give Les a call. (He doesn't use email).

T&L Engineering made a new oversize exhaust guide for me and machined the head to fit and fitted it; not to mention puttng in new seat to replace the turning stuffed up one. And stak of other work (like the collapsed head bolt pillars) and re-ling the barrel to standard etc.

It was a good job and now about 1,000 miles since and compression and performance improving as all bed in together.

I have no business or other relationship, just a satisfied cutomer.
