cam and cam chest gear assembly i.d.
Do all cams made by h.d. have identifing letters? Is there a way to tell if a cam chest gear assembly is h.d. or reproduction? (Including cam) considering buying a used set that looks to be in good shape. Seller says they are h.d. but they look too good to be true , even cam .cam has no i.d. marks (other than timing) nor do any of the other gears.they are supposed to be from a 60s panhead.thanks for the help

FL cams were not marked. H's had an H.
You will have to put it between centers (or on v-blocks) and measure its total lift with a dial indicator to be certain.
More important is to mic the journals not only for wear, but to be certain whether the inboard journal is for a bushing (.811-)or a needle bearing (a full .812+").
Most inboard journals are worn, which is no problem if you can fit an under-sized bushing to it.
But if you have a needle bearing model of right case, you will need to replace the whole cam billet, and always the bearing too while you are at it, for safety's sake.
Needle bearings were a great leap backwards.
