Well, my Fel-Pro 1415's just came today. I have a few questions before a friend and I do the swap
1. Do I need to completely remove the headers, or can I just unbolt them from the heads and the headers move out just enough so i can remove old gasket, clean, install new gasket. I ask this because I dont have jackstands, so I cant really get under there and disconnect the header from the midpipe as well. If I have to, Ill just get some stands, their good to have.

2. Any special tools that are needed besides a few wrenches? Trying to avoid finding that I need a certain tool and rushing all over the place to find it, lol.

3. What sealant do I need? Or do I need any? Everywhere I look (Hanes manual for exaple) doesnt mention any sealant when re-installing the headers.

I know to scrape off the old crap gasket, and what ever gasket residue there is before re-installing, and tightening the bolts starting from the middle going outwards. Any last minute tips? Thanks a lot guys!!
 
It is best to remove the headers from the H-pipe and then remove the headers from the heads. This way you can clean the area really well. If you leave the header bolted to the H-pipe I dont think you will have enough slack to accomplish much. You can get a pair of jackstands from Walmart for like 10 bucks and simply use your scissor jack in the trunk to raise the car.

Dont use any sealants. The gaskets go on dry. It is best to tighten the bolts from the center out, but evenly is more important. Those Fel-pro gaskets are really good. I once had my number 4 cylinder header bolts come loose and it started to leak. I just tightened them back down and the gasket continued to seal just fine.
