EXHAUST VALVE GUIDE NORTON 850 +.004 KWPM
Exhaust valve guide for the Norton 850 engine, +.004 oversize.
This is an exhaust valve guide for the Norton 850 engine, machined to +.004 oversize for a worn or re-bored guide bore. The KWPM notation on the catalog line ties it to that specific oversize spec, so it is meant for a cylinder head that has already been bored out to take it rather than a standard-size guide.
