Any value in 198’s?

Do those pistons use a pin lock ring? The OEM pistons, and the pistons I have do not have a lock ring groove. They are for press fit pins. (non turbo pistons). I'm pretty sure the Wiseco pistons have the lock grooves.

Charlie, the pistons in the cast crank slant with the Molnar 'long' rods are KB Hypereutectic 1 mm OS 2.2L pistons and they have a floating pin and lock rings
