I've moved apartments, and now I have a Garage

all the utility deposits and various other moving expenses ate my cash, but I'll have extra at the end of the month.
Alright, I'm trying to make a checklist of the things I need for the rebuild, I'm going to buy them all this month, and then complete the build with a friend of mine.
I now have some experienced assistance for the build, but I'm still working on gathering all the supplies
So far I know I need
Tools:
Torque Wrench
Torx Sockets
I have pretty much everything else.
Parts:
Gasket Set
Fuel Injectors (replacing/upgrading to 5.0 mustang injectors)
Plugs/Plug Wires
All the Hoses and clamps required for the Hose Mod
New Coolant
New Oil
Some of the questions I have are:
Should I have the head machined at a local shop?
Who can tell if my valves are bent once I remove the head?
Also I was wondering if there are any other tips before the build?
