It's not a difficult job at all. As long as you have a lot of tools and a little of elbow grease, and about 3-5 hours to spare, you shold have no problems.
The only thing that I can suggest to you is the following. Please PLEASE label each hose and nut or bolt that you remove. I used different color paint. I dabbed a DOT with a certain color on the hose that I was removing and the end that I was removing it from. That way when I go to put it back on, I wouldn't get them mixed up.
Other than that, It's all about removing nut and bolt after bolt and so on. Just remember that once you THINK you have them all, and try to lift the manifold off, you really DON"T have them all, just check and recheck to see if you have removed all hoses and bolts. OHH, there's also 1 bolt, 1 hidden bold towards th ebaqck of th emanifold, between the firewall and the manifold itself. you will not be able to see this bolt, you'll be able to only feel it. If you do not remove this bolt, then th emanifold will not come off. Good thing is that once it's removed, you do not have to put it back in.
Let me know if you need any more specific information.
