Stock rockers?
Sounds like a cam, lifter, pushrod, spring, valve or rocker....
Rockers, springs, and pushrods "look" solid. I've gotten opinions of rod bearings from other folks, and a dragster pro (at the track) mentioned wrist pen. I wasn't planning on it, but I may just buy an engine stand & pull the whole motor out. Buddy's got a hoist I can borrow.

nah pulled the heads and check the lifters...also pull the cam out and check it out...once i had that same noise you are talking about and it turned out to be some metal missing from some of the lobes on the cam
2006 silverado SS....Clifford Jr...turbo coming soon

Yep, I've seen that a couple times.
Didn't wanna commit to one single thing til I pulled the heads. Started removing some of the miscellaneous things around. Just got intake, manifolds, and head bolts left.

Going shopping for an engine stand tomorrow. Maybe I can catch one on sale. I'll see about borrowing an engine hoist. Only got this far... Didn't wanna break into much without being able to go all the way. Sorry for the crappy iPhone picture. Couldn't keep my hand steady enough.
