Well hedman tight tube headers slide right in , and so far have not hit bottom with ppes , they are about 1/2" lower than transmission pan , if that . The mechanics at the garage said if the pipes hit they are the least of my problems .
Here ia a link to pics of how they fit

Have to say car runs great , sounds great and header install was EASY ! Uncoated tight tubes are not expensive so it might be a good choice for you .
