I have Mad-dawg 2" headers on mine now with low deck 440-1's with a little mod. to #7 and #4. #7 had to be cut and dinged to miss the steering, and #4 hit the torsion bar. Besides that not too bad at all. I bought them off ebay for 550$ I beleive. They fit perfect with my low deck w/ stg 6 heads. This is all with rack-n-pinion steering so can't say about steering clearance.
