Umm, lets see now... off the top of my head you'll need:
- Upper engine gasket set (includes felpro headgaskets, valve stem seals and all the other gaskets you'll need).
- Head bolts (OEM are torque-to-yield 1-use only bolts). ARP studs are better and re-useable.
- Coolant & oil + filter.
- A place to take your heads to be checked and reconditioned (bring your valve seals from the upper engine gasket set with you).
- Some special tools 'n stuff (torque wrench, parts washer, power steering pulley puller/installer kit, silicone sealant etc,.).
That's all I can think of right now, but that should cover most of it. We did mine in one weekend, with the help of 2 other people, and it wasn't difficult but more time-consuming than we thought.
If you want to install new spark plugs, wires, or perhaps get your exhaust manifolds ported (highly recommended), now is the time to do it! Planning this all out beforehand will help the job go much smoother and faster.
Any more questions, just ask...
