Well I took the vc's off today. When this all happened, I *thought* it seemed like the pass-side is where I heard the 'bearings in a Folgers tin can' sound. Evertying looked fine under the VC's except one thing. ON the passenger side, second piston back from the front, the right rocker (which make make it the third rocker in from the front) is cranked wicked high. As in, the spring is super compressed, and the pushrod side is super high up. It appears way higher than any other rocker on the motor right now. Here is a pic. Where do I go next?

Hard to see but it looks to me like the valve spring on the affected rocker is the same height as the neighboring spring. Maybe something with the pushrod, lifter, or cam?
I'm thinking a broken valve too. Over revved it. Floated a valve. Piston smacked valve. Ate valve. Tossed it around the cylinder on the way down. Then locked the motor.
Spring and rocker seems tight enough. No different than the others. Can't figure out why my double spring setup allowed a float though?

Didn't mean to ignore the other reply. I'll pull the plug and analyze. Leakdown without the rockers how?
Just loosen the rockers all the way for that piston and pressurize it through the spark plug hole. It will probably leak so much that you won't really need a leak down gauge.
Ohh Ok that makes sense. So do you also think that it's a broken valve? I'll try to get going on a leakdown. I think pulling the spark plug will tell a story too.
Can somebody tell me why the rocker would be full up on the pushrod end if the valve is broken?

hydraulic lifters? if one was under pressurized or collapsed, pushrod could have wiggled its way to the edge, then oil pressure forced it higher than intended.. giving you the oil derrick effect on the rocker arm?
Really?I'd think that "what would come next" would be pretty self evident, but...

Remove head. You know you've got a broken valve at least, so head HAS to come off. At worst, you've got a caved in piston.

Remove rockers from that cylinder, inspect. If all looks fine (push rod) valve spring, stem, etc) then do the above mentioned, "poor man's leak down test".
That is if you have an android/non iPhone. Download an app called CameraFi.
Pull plug, shove borescope in there. See what you see. If you see shards of metal pull the head, the engines screwed.
If you don't. Pull the rest of the plugs and see which one is screwed. Lol
EDIT:
Dear mods,
Sorry if my links aren't allowed. I've used and abused my borescope at least 10 times in the 2 months i've had it, its a useful tool for almost anybody.
Delete my post if you will.

Two weeks ago I began tearing the top end down. I didn't have to get very far, taking the runners off in fact, to realize there is massive chunks of piston within the system. The runners and upper intake have massive chunks of piston. I also noticed the cam was ******* off of the distributor gear.
Thats as far as I had to go to know that the motor is FUBAR. I appreciate everybody's input and help in this.
