1. How do you press the rods off and new pistons on ?
2. How much torque do I use when attaching the rod and bearing back on the crank? (Is there anything else I should know here as well)
3. Do I need new bearings?
4. If the cylinders look in good shape do I have to hone them?
5. Is it even wise to attempt a rebuild without experience?

Engine had less than 80,000 miles on it before valve seat fell and killed everything.

Thats about it. I have worked on cars doing various things over the years. But have never attempted a rebuild.

know what your getting into its a pain without the right tools
1 cam shafts , lifters and rocker armrs-removal and installation
disconnect the negative cable from the battery
remove the air cleaner intake duct
remove the valve cover
remove the drive belt
remove the flange bolts and remove the fulcrums rocker arms, lifter guide retainer,lifter guides and lifters.Keep components in there originally installed
sequence by marking them with a piece of numbered tape or by using a
suitable sub divided box(such as an egg carton). If the lifters are not marked
with color codes, be sure to mark each lifter so you know which end faces the front of the engine, since you must reinstall the lifters so they rotate in
the same direction they originally did.
remove the ignition coil pack
remove the timeing belt
pass a rode or large screw driver through one of the holes in the cameshfaft
pulleyto lock it and unscrew the sprocket bolt. Remove the sprocket.
remove the two bolts and pull out the camshaft thrust plate.
remve the cup plug from the transaxle end of the cylinder head.
carefully withdraw the cam shaft from the transaxle end of the cylinder head
Installing the camshaft and rocker arms is the reverse as the removal
