I have a 95 z28 and im doing a full msd setup on it but before i start it i need to know if im going to need a special tool to pull off the water pump or any other helpfull tips to make the process go a little easier.

 

huh? The water pump doesn't need to be removed for a tune up.

Plenty of write ups about replacing plugs on here. I do the driver's side from the top and a couple of the passenger side. I get the rear 2 on the passenger side from below... (car on ramps).

I take off the alternator so I have easy access to the front passenger side plug.

That is pretty much it...

 

I think he means the Opti will be be MSD which requires removing the pump. I used all normal hand tools.
