Generation IV Internal Engine - can a cam be saved??

long story short my buddies cam only 6.0 gto got a new timing chain and a few other things and in the process the oring for the oil pump got pinched causing a lack of lube to the cam/lifters etc. the gto got a new cam and is back on the road but i've got another buddy budget building a lq9 and was asking if a machine shop can maybe polish a cam so he can use the old gto cam in the lq, I've never heard about doing anything like this but i figured if anyone would know it would be someone on here lol.

Tell him to not even think it. Just buy a new one.

Pictures of said cam would help. It really depends on the extent and severity of the damage.

I'm waiting on him to get these pics also, when he sends them to me i'll update the post. I personally havent seen it.
