Escape motors use the same crank sensor position as the 2.5L engines so there is no issue. Fitting the covers/engines shouldn't be affected by your choice of timing components. As long as you are consistent with each type they should work.
Both small and large pitch chains and timing components fit behind either timing cover.
You will only have a problem if you have a taurus/sable motor and left the pulsewheel stock for the taurus/sable....which would be to accomodate the left side sensor mount as you look at the crank pulley. Otherwise you will be fine.
