You have stupercharged in you username? If you have or plan to use boost then you need to modify the vacuum line with a check valve into the vaccum side and a seperate filter on the innlet side so that boost pressure isn't allowed to go back into the opti. Boost pressure into the opti will distort and damage the Optical wheel.

The longer drive pins can be bought from GM. Sorry, I can't locate that part number. Lingenfelter also sells them, or use too. you do not need to change the cam, 92-93 LT1 cams work with 94+ opti drives, only hte drive pin needs to be changed.
