Default spark plug gap
Is there any performance gain from changing the spark plug gap on a naturally aspirated motor. Is so, what gap? I heard this from someone and just want to know if its true.

Default
The gap spec is .040 in.

Changing the gap will have a negative affect performance and emissions.
