Your headers slid in?
Oh and what about y pipe banging? why do some bang and some don't? motor mounts, crappy header collector design?
Here's an alternative method to jacking :

For me, I had to remove the steering column. Do Motor mounts while you do headers! Here's my write up on how I did it:

My y pipe very seldom bangs on floor board when I accelerate from a stop. Not frequent enough to be a problem.
Probably couldve removed a motor mount bolt and raised the motor a little, but thought the steering shaft was going to be easier.
Some y-pipes bang b/c of different header/y-pipe designs and motor mount condition. If you dont want it to hit, after you get the headers in, hold the y-pipe in place and mark the pipe where it needs a dent to give some clearance around the floor brace on the driver side foot well.
OP, mods dont usually just "bolt on"...welcome to hot rodding.
