OK, thanks for everyone's input! I have looked through the top end and can not see anything glaring at me.

As you'll be able to see in the video, the cams move a bit against the tensioner, which I think means that the head isn't the issue. Next you'll see my 4 ft breaker with a 27mm socket on the crank pulley and putting quite a bit of effort to rotate it. If I go the other way the crank pulley bolt seems to loosen. I have also loosened all the belts and removed the CAS.

Also, the 4oz of MMO that were in each cylinder had dripped through, I added another 4oz to each cylinder tonight.

I am completely stumped, I just can't believe a piston could seize so quickly. FML...
