1) Order the full overhaul kit from www.rpmrons.com or a place of your choice. Measure the bores to confirm their diameter and get the piston set that is at least 0.010" oversize, when you place the order.
2) Drop the block, pistons, rings, rods off at a reputable engine shop.
3) Have the shop perform the usual block treatments, hand fit the pistons to the block. Also have them gap the rings for you, and press in the wrist pins. Maybe they can also put in the new core plugs for you. (about $400)
4) Bring the crank and cam with you to get a pro opinion on it's condition, or source good used ones.
5) That motor had low miles if I recall. The hydraulic posts should be fine. Just disassemble, and clean them out (look for my thread).
6) Assembly is the reverse of removal (no hammers needed)...except for the core plugs.
