With a quick glance, that looks like a good thread.
I did mine with VERY little experience, my biggest issue was the rust welded down pipe to cat back bolts that required a dremel cutting wheels and carbid drill bit, hopefully you'll have more luck.
Simply:
-KEEP your stock head gaskets (Do not use the ones with the kit)
-You will probably break the cross over bolts (oh well)
-Best to get (2) 3" and (2) 2.25" band clamps, got mine at Napa (as appose to the horseshoe clamps in the kit) (unless your getting things welded)
-Copper RTV is your best friend (use it on at all of the connection points)
-For the rear manifold, pull the engine forward and pull your Transmission tube, (I tried "bending" it, didnt help, and you don't have to go as far as removing the rear vaulve cover like some people talk about) I removed my throttle body too, and slid the rear manifold back there ...... eventually.
-You'll need an O2 extension for the first sensor on the rear manifold (got mine from ZZP)
-Patience.
-If I missed anything, Im sure ppl will chime in
Good luck.
