Sealing up 340

So i'm in the middle of replacing all my gaskets in my 340 and i'm not to impressed with the apparent thousands of dollars that was spent by the last owner. Found the entire left bank pistons with the notches pointing to the rear and the right bank pointing forward, the right way. Also found half of the rings lined up on the thrust side of the pistons. Fck someone paid for this great service! Makes me wonder
