Are we sure the gn250 top will bolt up with a gz250 bottom?

Interesting kit for more displacement. Do a little research of part numbers for the gaskets on the GZ and GN. If the cylinder base gasket and head gasket are the same you might have a winner. Keep in mind this mod might be very expensive overall.
If it is just a R/R then go for it. The increase in hp and torque would be really sweet.
