Cam repair.

I've got enough new old style alien lobes and pieces to replace a few of the heads on my cams. Anyone got a recommendation or idea who can do this.

no

That would be a phenomenally bad idea. If you need to do more than wires, triggers and slings, it is time to retire the cam.

There all in working order minus minor things, I just mostly want to use the parts

You see cams are not merely inanimate mechanical objects. Manufacturers actually use dark magic to produce them and if you try to replace any of the parts(like you would in your cars engine) the magic will fade and you will die. Unlike your cars engine cams are extremely complicated pieces of equipment and you should not toys with the dark arts.
