A 3K block can be bored 4mm or 0.160" - That's how far we went with our old race engine & the Tosco pistons.
I'm pretty sure that a 4K crank won't go into a 3K block though ... the rods will be too close to the skirts.
IF you use a 4K block, they're thinner walled and so not very strong. Everyone that tried using them in the Sports 1300 class had them crack around the expansion plug holes on the cam side.
If you use a 5K head gasket, that'll take the extra bore.
Have a look around for VW or motorbike pistons, there's plenty that fit.
