The schematic has everything you need to know about what is in the kit if you know the 1FZ-FE.
I'll make it easier for you.
This is what is in 04112-66036 (Valve Grind kit, 1FZ-FE: AKA: Head Gasket kit)
1. Head Gasket
2. Injector orings and grommets
3. Fuel line gaskets
4. Throttle body gasket
5. Exhaust Manifold gaskets
6. Intake manifold to head gasket
7. Upper and lower intake gaskets
8. EGR valve to intake manifold gasket
9. EGR pipe to head gasket
10. Fuel filter banjo bolt gaskets
11. Valve cover gasket
12. Spark plug tube seals
13. Valve stem seals (both intake and exhaust valves--24 total since it is a 24 valve engine)
14. Water outlet gasket
15. Thermostat gasket
16. Timing Chain tensioner gasket
17. Water bypass outlet orings (3)
18. Exhaust manifold down pipe donut gaskets
19. Air injection tube gaskets (for 1993-1994 trucks)
20. Gaskets for the cylinder head screw plugs
21. Dizzy oring
You need to add: water bypass tube gasket, oil cooler gaskets x2, oil cooler cover gasket, gaskets for the oil cooler plug and relief valve, FIPG for the half moons. Everything else that you add depends on the scope of the work you are doing and the scope of the plan.
