Spark Plugs

I am looking for a recommendation in respect of suitable spark plugs for my Tornado TS40 which is primarily used on the road. I am UK based.

Engine specifications are:-

Ford 302 Holley 600 cfm 4 barrel Big Valve Ford Motorsport Cylinder Heads (Aluminium) Motorsport True Roller Rockers Edelbrock Performer RPM Camshaft and Inlet Manifold MSD 6AL with Blaster 3 Coil ignition Accel distributor 51201E Blue Max 8mm Spiral Core Leads.

Also what would be the recommended plug gap setting.

Many thanks for your assistance.

John
