Installing Pistons on a PWC - arrow on top of piston?

I am installing new pistons on a Polaris Hurricane PWC. The WSM pistons have an arrow on the top of the piston. Should the arrow be pointing towards the exhaust or intake? Does it matter?

The piston is symmetrical except for a relief on the sides of the pistons around the pin area. The relief is offset on one side.
