Since you've got it all torn down you might want to consider replacing the shock tower braces with something nicer. I used Total Control Products stuff and really like it. I only did the braces that go from the tower to the firewall but they have more you can add later if you want. They offer a Monte Carlo brace and another support brace that ties everything together. Too much for my needs but it's all nice stuff.
I like them because they're so much easier to work around when changing plugs, etc. and the rods come out easily if you need more room to work, unlike the huge stock sheet metal pieces that are welded in.
Unless you're planning on removing the entire towers which is the way I should have gone! If nothing else notch them for more clearance, another thing I should have done. The Falcon engine bay is narrow so getting your hands on header bolts, plugs, plug wires, you name it they're hard to reach.
