not really, the hardest part is getting at the lower manifold bolts, you won't be able to get em all on with a ratchet, you'll be needing to use a wrench... racheting wrenches are worth their weight in gold.

Bolts 1–5 — 23 ft. lbs. (31 Nm)
Bolts 6 and 7 — 17 ft. lbs. (23 Nm)
Bolts 8–11 — 23 ft. lbs. (31 Nm)
Install the fuel rail and injectors.
Install the power steering pump and tension the accessory belt to specification.
Using new O-rings, install the fuel supply and return lines.
Connect all electrical connectors, vacuum connectors, throttle cable, cruise control cable and transmission lines pressure cable.
Install the air cleaner assembly.

It's a little different for the header... but it does come with instructions.

You need to know tightening order and torque settings, yes. though because on the header you will have to do some of the torqueing by feel with a wrench. using a stock exhaust manifold, use the pattern provided, it will help. Using an aftermarket header, use the pattern that came with the header, yes... that will help too... not doing so will void any warranty you may have had.
