I'd say currently inconclusive.
Machine shop was leaning towards valve failure. Victory performance is interested in taking a look at the valve train.

Is the top of the piston beat up? The first pick it looks like something was bouncing around and hitting the valve... the other one well...it was ****ed and folded in half...

Could have been much worse, if the valve head hadn't "hid" in the port. When I had an intake valve separate like that (my very first blown iron Pontiac) the valve head apparently didn't try to "hide"- broke a whole corner off the block!
I sure hope you make it to Norwalk. I've been waiting to see it run.
