Blown Motor.
#12
Nah, if something was in there during the build, it wouldn't have made it to 5k. If it is running too lean (intake leak), you can burn pistons up. What color were the other plugs? Your push rod bent because the valve contacted the piston at TDC, as it came apart. Chances are good that the head is cracked now as well.

You ain't gonna buff that one out... That sucks.

28 oz engines were made up until about 79' to be safe. maybe 84, but 79 and earlier will be a definite. might take crawdad up on his offer.
