With some modification it will, different cam chain parts and you will lose some compression. Others will have more info.

Do search for "J-model head swap" or the like and you should find all the answers you need.

Unless you plan on other mods to the motor for performance increase, it's not worth the cost & effort.

Those other mods would include:

New Pistons
Larger Carbs
Cams


For the money you'd dump into doing the J to KZ swap, you'd get better performance out of drop in cams on the KZ motor...
