hello all, I am finishing up my new motor and I don't know what spark plug would be best. my combo is windsor jr heads, typhoon intake, f303 cam 2 degress advance, with msd cap,coil,and box. And fms wires. the spec sheet for the heads say accel 276, but I have never used accel stuff so I don't know how reliable or well they work. any help is greatly appreciated.
