[DeTomaso] stock valve stems??

[Larry Finch]

 When I removed the 40 year old stock aluminum valve stems on the Fresno restoration car,
despite oil on the threads, there was some aluminum to aluminum galling. One is thoroughly
ruined and two others are damaged.

Does anyone have good stock valve stems they would sell?

Failing that, does anyone have success on a specific metal valve stem for the stock Campys?
Brand? Part #? Source?

Thanks,

Larry
