Yes much easier to have a shop do it.

You also mentioned it being dirty inside the engine. That combined with the condition of the cam would make me tear it completely down. At least pop a main cap or 2 and have a look see.

Looks like somebody used it as a hammer in a prior life, wow, that's bad.
GM's cam bearings caused a lot of problems early, I don't know if they've fixed 'em or not. Several wouldn't even stay in place.
I'd pull the engine and tear it down completely. Have it cleaned, new bearings installed (ALL BEARINGS) and analyze the rotating assembly prior to reinstallation. As long as there isn't a lot of piston scuffing or damage to any bores, drop 'em back in and zip it up. Post pics if you have questions about anything.
Oh, and a new cam, that one needs to go on a wall somewhere with a frame around it.
Genuine GM LS7 lifters can be had for under $150/set, yours can't be worth much after riding on that scabby cam.

That can looks like it was used as a tweaker-be-good-stick before it was put in the engine. Scrap it, and make sure everything inside the engine is good and clean.

I still think it was a tweaker-be-good-stick... and if it wasn't, then well it's now got a new job, because it shouldn't be used in an engine ever again.
