1.3 to 1.5L aka k3vet to 3sz internals, deck height etc

Hi Daihards! new here and searched but no luck so my apologies
if someone or a thread already exists, if so pls link and delete mine.

Anyone know if the K3 can just use all of the 3sz internals
or is the deck height different? I found a video that they say
side by side that rods and pistons along with crank
is all that is needed.
