for the K motors, there are different strokes and bores.
increasing stroke comes with a taller deck height. bore spacing is the same for all. the bigger motors have wider skirts to fit the crank in.
fwiw, between 3K (1200cc) and 4K (1300cc) the difference is 10mm deck height.
grab a 3S and 5S gasket from wherever, line em up. make sure oil and head bolt holes line up.
then find pics of the front of the motors (or better yet, tak your own pics) and make sure timing covers/gears/belts ans shit will swap over nicely.
what you wanna know is if the bore spacing is the same (likely), if the stroke/deck height is the same, if the front bits can bolt on.
if crank is bigger, but deck height is same, then you can swap easily, if not you need shorter rods or pistons with lower pin height.
you also want to check if the pistons are dished/dome and what volumes they are, and also the combustion chamber volumes etc..
in the K series, the 4K has a flat top and dished piston version, and 5K/7K are dished.. which makes direct swaps more interesting..
anyhoo, don't get put off just cos no-one else knows 
take a 3S gasket to a wrecker (u-pull-it type) and rip the head off a 5S  , measure deck heights etc...
