Hi ive got an L98 Small Block. 53 000 Volt Ignition coil. Its time to change the plugs. I have light mods. I had great success with the AC delco plugs I got from a gm performance parts dealer but it was quite pricey. A friend of mine builds nascar engines and all he says is always go copper. Especially with the kind of voltage I am running.

would I be best to just buy delco coppers and change them more often?

would it be a great idea to increase the gap a little since I got the juice behind it?
