yes, have to separate pistons from the connecting rods in order to split the block halves...or at least that's the preferred way. i've separated them before other ways...involving pieces everywhere, LOL
pull that hex port open and pull the wrist pins....don't know another way.
you can pull it partially apart...a few inches or so before the pistons catch. i've never tried to pull it as far apart as possibly and access bolts that way..between the case halves...??
here you can see the bearing surfaces for the crank and how they are in the way of the piston coming through internally:
