Or Autolite's 3924 not only work perfect but you won't notice
a loss of power on motor.

Start with the plug of your choice and take a full power nitrous run, then, pull any plug and look at the heat line on the ground strap. You will see a very definite line. That line should appear a little below the 90 degree bend. If it appears above the bend (or not at all) the plug is too cold. If it appears close to the threads, it is not cold enough.
