the header installation thread.. well, ??? anyway...

i want to get a set of headers for my car, but i was told that you build the motor, then get the headers according to the motor. but i was just going to buy a set of full length headers for my car and install them right before i go to the muffler shop to get exhaust redone (the right way..)

how hard will it be for me to get the headers on my car? (the car as seen in my sig :) ) i dont want to under plan for installation time on them.

i had planned on lifting the back end of my car by moving the axle perches and axle to the bottom side of the spring instead of the top. and i was going to put heavy duty shocks on the back end of my car.
that being mentioned because i guess it would give me a little more ground clearance for the tubes from my pipe organs...
