You shouldn't need any special tools. Just common hand tools like a ratchet and socket set, wrenches, screwdrivers, and pliers.

You'll need piston, piston rings, gaskets, wrist pin, and circlips. You'll want to get the cylinder bored in case it's out of round or tapered. You'll have to get over sized piston and rings to match the size of your overbore, but you can get the kits like Red posted above, but make sure they match the size of your overbore.

Wouldn't be a bad idea to replace the timing chain and tensioners while your there.

Yeah, that wouldn't be a bad ideal at all. That completely slipped my mind. If the piston and rings need replaced, then no doubt the timing chain and tensioner does, too.

do u have to torque the piston bolt on or do u just tighten it like a regular bolt with a ratchet
Not sure what you mean by "piston bolt", as the piston attaches to the connecting rod with a pin. The pin is held in the piston by a ring clip on each end of the pin. The bolts that bolt the head to the cylinder need to be torqued and it's a good idea to torque the rocker cover bolts, too, to keep from over tightening them and stripping them.
