454- Removing the air injection pump

[RCC1]

Does anyone know what size plugs are needed to remove the air injection from the exhaust manifolds on 1993 454 SS truck?

Also does anyone know belt is required to remove the air pump?

I once deleted the air pump system on a 305 in a car. I just cut the tubes off near the exhaust manifold and welded the tube shut. Looks the way it does, but works!
Rockauto lists several brands of belts for your truck w/o air pump.
