Spent an educational half hour on the phone with Randy Long.  He will be doing my heads. Seems Kibbkewhite stopped making valves for the less popular machinery. That includes Moto Guzzi. Plenty of intake valves are available, but the higher stressed exhaust valves are sort of used up. Randy said he will come up with a suitable substitute.

I've been buying valves from Stein-Dinse/MG Cycle for all of my rebuilds. According to the guys at the machine shop, they're excellent quality. Never had an issue with any of the dozens I've installed.

I use the guides they sell as well.

A good quality shop can put valve guides in. Ask around to find the “go to” local shop. The MG and VW car crowd will know who to use.

I've been running two sets of k lined guzzi heads for many miles ...zero problems and IMHO a very good solution.
