Any recomendations as to what Spark Plugs I should use on my engine with GT40 Y303 heads, part numbers? Im running a Jacobs 5.0 Ignition System so I cant use any preciouse metal plugs. Im also packing 10:1 Compression. Any thoughts?

A good copper plug will always be the best. Most guys with performance engines usually run Autolites. I don't know if it's the same with all aluminum heads, but the plugs I will be using with my Edelbrock heads are Autolite 3924's.
