Alright guys I finally pulled the frame so I can dig into the motor. I started at the front cylinder and removed the head. The engine spins freely. I put the head back on. The engine locks up. So I think I have it narrowed down the the head or the push rods. I am more inclined to believe the push rods are the issue because there are no contact marks on the piston or valves.

Someone please enlighten me!
 
Kind of sounds like a bent valve. Did you check, while you had the heads off, that the valves closed completely? It sounds like there is a problem in the #1 head. You might have to get the valves out and see if they are straight in the end.

An easy way to check the pushrods is to roll them on a flat surface and see if they wobble as they roll.
