I went with Hooker headers, from Advance Auto parts. They fit nice, and had the perfect clearance for my clutch linkage. Heres the downsize: Install was easy (as it can get shoehorning a 351), but I had to have the drivers output area bent slightly from an exhaust shop. The headers were around $250, and the bending was about an eight of an inch away from the frame at $40. I also relocated the brake line riser and just went without it. If you go this route, bend your own brake lines, then install the headers!
