Hopefully you didn't see Brians unreasonable answer before I removed it.

Gaskets/things to do while you are there.
New set of coolant elbows (Dorman 47065)
Fresh TB gasket
Check/replace any old/bad vacuum lines
New fuel injector o-rings (es70599 need 3 packs)
If your valve covers are leaking, it's also much easier to do them with everything off.
