Sorry, I didn't realize there was a question. 😴

Are you doing this with the engine still in the vehicle? Not saying it can't be done, but I can't imagine any other way worse.

To answer your question, it is difficult to say from the pic if the crankshaft keyway is properly located... I would need to refer to the the block/head assembly on an engine stand I use for mock ups.

Presumably, the number one piston appears to be near Top Dead Center, but without the remaining components installed and properly timed, it is meaningless. Ford made a special tool to slide onto the crankshaft to hold the crank in position during the assembly process. Most utilize a piston stop, a dial indicator and/or a degree wheel to properly set TDC.

What did you do with the heads?
 
I see. The heads have been rebuilt; looking to pick them up in a few days. I follow what your saying though and will search for that crank tool you mention to hold crank in place. Thanks for feedback; I will report back very soon.
 
Hello again, . So far after getting heads rebuilt I've got the heads mounted but gees am I having hard time getting exhaust booted on the passenger side. Lol. Anywho, wanted to share progress.
Heads
 
Nice. I would have thought that getting the exhaust off the head would have been the hard part.
 
I have had the exhaust manifold gaskets replaced with the engine in the vehicle, so I can appreciate the challenge. ;)

I hope you marked the camshaft retaining caps to maintain their OEM position(s)!

Be sure to verify the cams rotate relatively freely once installed(without the roller rockers). There should be very little(if any) 'slop' in the camshafts once mounted. If I recall correctly, the maximum radial clearance is 1.5 thousandths. I had issues once when there was 2-3 thousandths clearance which required remedial work.
 
A challenge indeed, in all honesty I cut the exhaust below the catalytic converter near the transmission thinking I could pull out head and manifold together. Starter did not allow for that.. I set aside cams, lifters and retaining caps in same manner they were in to put back OEM way
