Turn the engine so that the IP lug is in the port window and remove the IP.......carefully, so it doesn't rotate.
Rotate the engine so that the damper reads 15°ATDC on the compression stroke (cam lobes basically upward).
Reinstall IP.
Check IP timing again.

When you remove the IP, the IP cam WILL rotate. You need a special tool to hold it in position. The plunger springs in the pump will push on the cam and turn it away from that 15 ATDC installation position. It will not stay there by itself.
Agreed that the if the cam mark is aligned with the bearing cap mark when the crank pulley reads 0T you do not need to change it again, even if you changed it before. Once you retime the IP, the engine won't know that the cam was ever changed.
