Dear God!!! Don't run that!!!!

Sounds like it spit out a shim to me as well... the sound like rattling pocket change gives it away.
If it is a shim don't be surprised if you need a new cam.

that sounds gorgeous... uhh so i should replace a few valves and you think theres bad lifters too?? and possibly a cam.. im just tryin to get this asshole running for now, ill be doing a complete bottom end reinforcement and head rebuild around summer but for now i need it to get to work and back -_-

im gonna need to drive it to my friends house about 3 miles away to get into a heated garage with tools.. would that be horribly bad to drive it that distance? we should have the valve cover off today.

Tis up to you dude. If I were you though I might want to consider towing it since every revolution of that cam is going to increase the possibility of damage to the head or it's components. From the sound it's already "bad", so it's just a question of how willing you are to risk driving it from "bad" to "worse".

Feel lucky punk?

It could trash the whole engine... lots of metal getting shredded and the material getting dumped right back into the main system.
