your making this way to hard here ?? who cares if 12 and 12 is tdc on 1 you do not need to know that. what you need to know if the cam timing is in phase with gear marks and when you degree the cam that the numbers come in to the sheet on the cam card or work out the numbers. honestly i could care less to were the chain is marked to what cylinder is at tdc when there marked as long as the cam is in phased . built a hell of alot of engines not giving it any thought . dumb ? there dumb thing that make engines fail like no piston to valve clearance . rods out of round. the long list of dumb thing. dwelling on this is not helping you. if the cam is in phase . the engine still has one low bank that has nothing to do with wasting time on why the marks should be at 12to 6 for #1 and not #6 you have ether bent valves/pushods on the one bank very will could be bent intake valve .or a wiped cam on one side. hard to think all holes are low on one bank less that head had wrong springs on that bank or adjusted so far down all valves are not closing . if you did wipe the lifters do not force many out if you do you will cut the bores up.
