84 Kawasaki kz750 cylinder head to 84kawasaki zn700 compatibility

Will the cylinder head from an 84 kz750 swap straight across to an 84 zn700A? My 700 has popped the #3 plug & completely obliterated the hole. But I've got an 84 kz750 complete engine sitting right beside it. But before I started ripping them apart I was curious if it was even possible. That way I'm not out 2 motors.....
The 750 does run but has a low compression as well as a knock in the lower end. The 700 is my daily rider,but with the exception of a FEW minor mods. Carbs from an zn1100,modified exhaust.....etc.
But will it basiclly pull off of one to retro fit the other without very much hassle?
Thank you for any help at all....

Before you do a engine or cyl. head swap i would try a Time Sert insert repair on #3 plug thread and it will safe you some time and Money.
