Pulled the engine out and flipped it over on a stand, and just pushed the pistons down enough to get the rods out of the way of the crank. I've got 2 timing marks on the camshaft sprocket and they are 180* away from one another. I've even tried using the other mark , and still no difference. I'm putting some marvels mystery oil in the cylinders to let them set tonight hoping it will allow the rings to free up.
