It's not turning over enough to be hitting a valve. It looks to me like it's something in the bottom end. Can you loosen the oil pan? Maybe if you can just lower it a bit and try to turn it over that might help. I know to remove the oil pan you most likely need to pull the engine. You could try pulling the motor mount bolts and lifting the engine as much as possible, that might be enough to pull the pan.
If you did not have this problem before swapping the heads & cam I would vote for having dropped something into the oil pan.
Good luck.
Keep us informed.

IMO the sound in the video definitely sounds like something in the oil pan getting jammed up against the crank. The "bang" is very solid, hollow, and tinny. Now if that's true it would probably be hitting in the front where the pan is shallow. If it was something in the back where the windage tray is I don't think it would sound that solid.
Have you had the oil pan dropped at all? Not sure if you did the oil pump, but if you loosen all the pan bolts it will drop ~1" or so before it hits the k-member. If you do that and stick your head up from underneath and use a flashlight, you should be able to see anything sitting on the shallow part of the oil pan. Just lower it slow and listen carefully so if there is something in the pan and it starts to roll, you'll hear it.

I put the car in 4th gear to remove the crank bolt. I have since removed it from gear to try to get the crank to turn.
I am going to lower the oil pan tomorrow to try and have a look in. It is still attached to the oil pump, that I can see just from having the timing cover off.
Guys, I really appreciate the help. Thanks a ton.

Oh man what a bummer, been there.
Long ago had to pull the engine back out, tear it down and find out an oil restrictor (BBO) had backed out somehow…
But the hassle of pulling it was worth the peace of mind. With the engine on the stand, everything goes so much smoother.

Well, I got my answer today. Number 7 piston isn't coming back up when I rotate the crank. FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF FF!!!! The car ran perfectly fine before. I didn't touch anything in the bottom end. How is this possible? Was I down a cylinder and never even knew it? The car never acted funny, not once.
