Since I have to replace the head...
I'd guess since #3 is TDC, that one would have both valves closed for the power stroke, right? I don't trust the cam sprocket alignment on my existing cam (to copy it for a "new" head) given it was turning at the time the pistons hit the valves and since there is no keyway, it probably twisted. I'm just not sure how I'd get everything lined up just right to time it properly if the cam sprocket and torque plate has been removed by the wrecking yard. I'm amazed there aren't alignment marks on the cam, sprocket, and torque plate... (or am I wrong on that? I hope...)

That makes me feel a bit better -- if the plates are keyed, then it should be a cinch. I went ahead and bought a head on ebay. I should have it in a couple of days. I guess I should start tearing everything else down.
