No machining, nothing will be warped.
You need a torque wrench capable of 10-20 ft-lbs.
A manual would help.
You need a LIM gasket set (all 4 pieces), a SC gasket, 2 yellow o-rings, fuel injector o-rings, and a TB gasket (if you plan to take advantage of the TB/MAF techinfo at the same time).
The Fel-Pro set if I'm not mistaken will provide you with everything but the fuel injector o-rings and TB gasket.
You will need 10mm, 13mm, and 15mm sockets. Nothing else. You'll learn how to double-nut the stud in the nosedrive that goes through the accessory bracket. Also a good time to replace the SC coupler.
