Head-Lock

Unless Marz redesigned their steerer tubes, the head lock won't fit. When I bought a head lock for my DJ bike (with Marz DJ3 fork), I took my Dremel and ground down the area that inserts into the bottom of the steerer tube...a little at a time...until it fit.

just pick up one the double star nuts, ive had 0 slippage..

I like the Azonic Headlocks, which is why I was a little dissappointed when I realized I couldn't run one with my Pike. Just grind down the base of the headlock until it fits the narrow ID of the Marzocchi steerer.

I really think one from Planet-X would fit, they have a different base nut design than the azonic. that and its lighter. PS, I have both. and that fork. Just havent tried the two together yet.
