The above said is true on Naturally Aspirated motors... On vehicles with forced induction, such as the Turbo engines, having a slightly lower compression may be beneficial because more compressed air can be forced into the cylinder... However, finding the right compression is key, and getting a thicker gasket is not the way to achieve it. You'd want different pistons for that
