This is a very common set-up to gain more performance as the J-Model has a larger combustion chamber and larger valves and a much stronger head than a KZ.
To do this, you must use a J-Model Piston with a .060 spacer under the block to make up the difference in piston deck height.
Can I run a J-Model head on a KZ bottom end?
