I reread my statement, and didn't really intend to sound SO negative. I'm just a hotrod guy, and headers are about the first thing any hotrod motor of mine gets. I really wouldn't want headers on a regular daily car of mine though. There's a very strong line between a daily and a garage beast at my house.Nad, What do you have against cast iron?
Try NGK spark plugs they are shorter and will give you the clearance you need so you will not burn you're plug wires.I'm running the Hedman Headers, no leaks so far. Getting to one or two of the plugs is a little tight. I also used heat insulation on the plug end of the wires.
