Looking at the valve cover damage, its hard to tell, but maybe ice hung up the rocker arms, or was in gear high enough to stall the motor and prevent further damage. Luckily, used motors are more common than used FD's and pretty cheap.
Engine was shut off immediately. When I adjusted the valves, compression was solid. As soon as I get my new coil, ill fire it up and let you know.
