Now for the part I missed - Roll the crank 360 degrees (that's half a rev of the cams) and see the other side. Now the cams are set 180 degrees out from one another. I have one set of cams out 180 degrees. BYprodriver hit it on the head.

I really wonder if the motor is a interference motor when the instructions tell you to just rotate the motor 360 with no regard to cam position?

Trust that it is a heavy interference engine.
Not rotating the engine when setting cam timing only phases both banks of cylinders simultaneously.

This creates two 3 cylinder engines and the engine would run if it had batch fire injection and a wasted spark ignition system.

That sound on the starter tells the entire story when this occurs.

It doesn't take much -- a properly set engine whose IMS Sprocket slips and rotates slightly
will take out all the valves -- so this tells you that the clearance is very tight.
(it's one of Jake's 99 millions ways these engines fail :-)
