I completed a top-end rebuild of my 79 Corvette. Bigger cam, Performer Intake Manifold, 800cfm QJet Carb, Headers, and AFR 180cc Street Eliminator Cylinder Heads custom milled to 60cc. AFR recommends AC FR3LS or 41629. Are there any good suggestions on spark plugs that I can get locally with the AFR Heads?
 
Well I decided to go with the NGK FR4 V-Power Plugs. The one's I pulled have a bit of white residue on them so it appears that I am to lean even though the idle mixture screws are set properly.
