Ya that's pretty much it...oh and make sure you follow the tightening pattern on the manifold bolts (start from the inside and work your way out) there is a wiki link that I will try and find that could be helpfulThe heatshield can suck coming out.
Use the very first O2 sensor in the new header.
The old manifold comes out the top. (it can be a tight squeeze)
Use anti-sieze on the bolts
