A body header choice PLEASE HELP

Love my Doug's. It was ridiculous to pay an extra $300- $400 for TTIs in my case and for my 74 Duster.
Ive had both and I like the dougs better. The only tweek I needed on my 74 duster was at the collector. Mine have a slight downward tilt but im running a 360 on conversion mounts with a slant 6 k frame. And only on the driver side.
