You can install the 600 HO cylinders on the 440 case, the case will need to be decked to achieve proper install height.
What is "decked"?

what about 600 ves cylinders oor do i have to do the same thing
Decked is to machine the cylinder side of the case to remove material to lower the cylinder on the case.
600 VES cylinders will require the same procedure. 600 cyls are .100" taller than the 440's due to rod length/port timing. The 440's use a 122mm rod whereas the 600 uses a 128mm rod.
440 case with 122mm rod and 600 cyls requires the case to be decked/shaved/machined approx the height difference of the cylinder, give or take upon desired port timing specs.
Another way is to install a 600 crank with longer rods (128mm 600 rods) and build a spacer plate and gasket set up to make up the height change on the case.
