Thickness depends on the application.
General rule is to put in what came out to maintain original clearances.
However , if you have enough clearance between the crankcase and any moving parts on the externall part of the crank then a slightly thicker gasket should not adversely affect the operation of this engine.
Lets note that a too thick a gasket however will increase the overall volume of the crankcase by 1 or 2 poofteens.
