If it's the same 'block' style chopper cylinder we have, I've rebuilt a few heads worth on the Gauntlet, just needed a good cleaning and lubrication. Be smart to get at least one seal kit just in case before you dive in, it would suck to damage one and be down a head.
Needed snap ring pliers, and got by with a bike cone wrench for getting the clevis off the end of the rod--although you could always grind down an open end and get a little more purchase with a better home-made tool. You don't want to leave a burr on the end of the rod when you reassemble...
