well first tip your case over and get all that oil out of there... shouldnt bet that much, second, are you using the correct head? did you have the right head gasket? it seems that the head might have been leaking, it shouldnt have all that brown around the top f the cylinder. so take out the oil, just let its sit up side down, and then clean off the cylinder head with a wire brush, change the spark plug, clean the top of the piston, make sure no rings are sticking into the ring grooves, clean out the exhaust port CAREFULLY! and then blow into your exhaust and make sure it flows freely, if the exhaust is backed up, it will make the engine run bad, have bad power and would also make your top end get covered in carbon, just like it is, it might have also caused all that excess oil in the bottom.

I Second MySprees comments. Have you tested your compression tester?

It is normal for an engine with new pistons and/or rings to read lower compression. Remember that new parts (rings, pistons and cylinder) must seat in before full compression can be reached. To seat in the parts the engine must run for at least 200 miles at half throttle (see manual). The object is to wear off the rough spots and seat the rings to the cylinder. Too rapid an acceleration will knock off too large a piece of the rough surfaces rubbing together and scratch or score the cylinder. As the rough surfaces of new parts rub together they produce more heat. Heat draws the temper out of the rings and can warp pistons and cylinders. This is why full throttle with new parts is not good. After 200 miles at half throttle you should have highly polished pistons, cylinders, and rings that seal tightly against each other yet can move very rapidly with little friction producing superior speed and power.
