400 big block + my 71 Demon

Schumacher headers (which I use) have the easiest fit and works well even with power steering for street and light strip if you're not looking to squeeze every last 10th's from your car. TTI's 1 3/4" headers supposedly fits both B and RB engines, but only the B engines with power steering. TTI also make 1 3/4" and 2" that fit manual steering only. Although none of the above are cheap, I'd rather spend more on something I can use than half that price on something that I will have to beat to death with a hammer.
