Correct spark plug gapping?
 

i just replaced my stock ignition coil and cap and rotor with MSD parts and i was wondering if i had to open up the gap on my spark plugs to enjoy the full increase of the extra spark voltage.

Nope leave it stock gap. The extra voltage is for high compression or S/c or nitrous so the extra fuel and air don't "blow out" the spark.

thanks i was just about to do that today once i got home.
