The problem with any sohc pistons aftermarket or otherwise, is the 2mm thick compression rings and oil control grooves weaken the pistons in the ring land area.
Dohc pistons have thinner compression rings and oil control holes rather than slots which result in a much stronger piston than the sohc version. The down side is that the dohc pistons don't have valve reliefs in the right spot for the sohc head. If you use atmo dohc pistons you will have to fly cut them to prevent contact with the valves
