You'll need the following:
Vented Opti
95 Timing Cover (96-97 can be used, but you need to plug the CPS hole)
Vented Opti Wiring Harness (this has a plug about 2x as long as the non-vented) -- Available from Caspers Electronics for about $30 as opposed to GM's $60+ charge
Opti Vacuum harness
95+ Cam w/longer dowel pin (GOOD opportunity for a cam swap)
95+ timing chain, or a LT4 HD or Cloyes (Cloyes set is only like $70 for the doube roller from Summit)

You sure that 80$ cloyes will work? I just looked it up on summit and its not a roller. I thought it had to be? Here is a link.
