Just be sure the ring grooves on the pistons you install match the thickness of the rings. A dial caliper is your friend here. Parts don't care where they fit, as long as the specifications are correct. I routinely mix and match parts from different manufacturers, such as using Ford 223 cubic inch pistons in a Chevy 235 to accommodate a change I make in the crankshaft stroke with a different wrist pin height on the piston. Be sure the sheet metal pushrod cover on the side of the engine is the same shape- - -some 216's used a short cover, while others had one that went all the way to the top of the cylinder head. As long as you order pistons and rings for the same year engine you should be good to go. Why do you want to swap? Maybe a bad cylinder head?
