Who has 9 or 10 deg valve collets (locks) that fit Norton valve stems? These used to be available.
 
Summit racing has Manley 10 degree valve collets for 5/16 valves, part # 13151-8.

I should have said that info was the result of a basic Google search, I have no experience trying to fit them to a Norton valve.

The 13151-8 summit racing collects have steps in them and won't work. The 10 deg Norton collets used to be available for Norton aluminum retainers. I raced with them and they worked fine. I want to use the 10 deg collets with titanium retainers on a super shortstroke that has a potential of 10,000 RPM.
 
Kibblewhite has them. They used to list them separately in their catalog, but the latest one doesn't seem to do so. The part number is 50-0462, "H.T. Steel Keepers". Those are the ones they supply with their aluminum retainers. I think these are the ones Jim Comstock is referring to in the thread linked above.
