MSD or Taylor wires are typical on here.

How many people have had success with MSD wires..I do run across quite a few post/threads where people have had problems with them. What are the advantages of the MSD over the stock wires? I've been using the NGK TR-55's and stock wires with no issues.

Any wires are fine, our wires are so short that it really doesnt make a difference which ones you get, the resistance is close with all of them.

As for plugs, the TR55 is popular with most people around here.

when i went to go buy my ngk tr-55 spark plugs, the salesperson at orilleys told me the gap was .50, and that they were already gapped, so i did not mess with them, do they come .50 or .60??
