If you turn your crankshaft a little 1/16" counter clockwise, I think things will line up fine.

Marking the belt and sprockets like you did is the best way to ensure you got the timing belt back on correctly. No one I know ever uses a timing belt that has close to 50,000 miles on it.

My opinion from the pictures is, make the timing belt tension adjustments (2 different times-one extra tight and a final tightness where the 2 pointers line up) rotate the crankshaft 2 to 4 revolutions clock wise with the spark plugs out. This will sort of seat the timing belt idler pulleys and not bend your valves if something is not aligned correctly.
