I learned long ago the trick to installing 4 into 4 headers (although I had to be reminded of it this past spring)

1: loosen the header bolts so you can wiggle the header tubes.
2: Install (loosely) the rear bolt on the side pipe itself
3: Spray a light coat of PAM" cooking spray on the inside of the side pipe flange, and on the outside of the header tubes. You can spray it o a rag and wipe it on both pieces if you do not want to get over-spray on everything.
4: With the car either on a set of jack stands or wheel ramps in the front, slowly slip the side pipe to header tubes on while you are under the car. Each one is slightly longer than the other, so the first tube to hit is the first to get aligned, the second, third, and then final tube.
5: The header tubes should now be firmly within each associated side pipe tube. You can now wiggle the side pipe to get the bolt flanges to join each other.
6: Now bolt the flanges together (make sure to use a lock washer).
7: once flanges are firmly bolted together, retighten your header flanges to the heads.
8: Finally, install and tighten any rear mounting tab bolts, again remember to use lock washers.
9: Fire the car up and listen to how good the sound is.
10: Clean up and get yourself something to drink, you earned it.


Yes, it really is that easy.
