Just follow the instructions from Sean exactly. I can't think of anything that isn't in there.
It is worth it to remove the hood. Just do it, you'll thank me later.
Also go through your injector wiring harness. Clean it well and rewrap any exposed wires. Replace the injector clips.
Change out the thermostat for a 170 or 180 degree and replace the gasket. Its the best time to do this while you have the manifold off.
It may take longer than a weekend, definitely if this is your first time. I can do it in about 5hrs now, but I've had mine off and reinstalled 4 times.
If you are installing a VEC at the same time, add an additional half day.
I'll be around all weekend, you can PM me any questions and I should be able to get back to you quickly.
