I seriously doubt you will see any performance difference you can feel or measure by changing the thickness of the base gasket. I would not consider it a tuning tool.

The head clearance is where you will see an increase. If it’s optimized to the minimum without hitting and, centered on the bore, it will burn more efficiently and that counts for allot.

Increases in compression ratio (to a point) will benefit the lower rpm band but the increase in compression ratio from a gasket change is minuscule.
