I agree with ROB, I take it your currently using your SSAC. If thats the case, you would have to buy another and spend around $125(used/new or even shipped). Then pay to have the header reworked + materials. then maybe a little dyno time to figure out if the header was worth it.
On another note if all you have to pay is for the header and a friend will do it all for free than have at it, you cant go wrong.
