Need new plugs

Got a 95 Z28 and need new plugs in it in the worst way.What would be the best ones to get.Was thinking about the E3 Diamond Fire plugs,but thought i would check here and see what you guys recomend first.

Already have the wires,using the MSD Super Conductor 8.5 Wires.

Stay away from "gimmick" plugs. You will get the best results with a simple, single electrode plug. Many people with stock setups have good results with the NGK TR55 Iridium.

Be sure to check the gap, before you install them. Stock spec is 0.050".

Your CarDomain site indicates you have ported heads. If you are over 400HP at the flywheel, you might want to consider a 1-step colder plug, which would be the TR6.
