The "tall" head will make very little difference if everything else is the same, especially w/ flat-top WC/WD type pistons. With the WD45 crater type pistons it does direct the spark toward the center of the combustion chamber.

now that we've told everyone how little we know about ignition,squelch area,and flame travel.the spark plug location is the same. the only way you could benefit, would be if the runners were different.
