I went with "Headman" fairly cheap ($55.00 if I remember right) with excellent fit. The only draw back is you will loose a bit of bottom end torque as they are a shorty type header but, if you want maximum clearance than you'll have no problems. I've had these on for about 4 years now and have only had to adjust the header bolts once.

 

are any of these headers 50 state legal? and a have a c.a.r.b tag on them?
