The Muzzy gasket is know installed, and the head is currently torque to spec. Just need to put the cams, and the rest of the parts in. It wasn't hard at all. I've put in 10.5 hours so far. The manuel instruction left a few things out for sure, but nothing crazy. The gasket is like the 636 trick. Instead of three layers, it's only two. My Pitbull stands f'in rock. The bike stayed still the whole time. The head bolts are on tight. I lost a lot of time trying to figure out the gray areas.
