I'm probably going to hate i ask this question, ( i did search, three times) Has anyone had any experience with the Dougs D669y Headers? They claim to fit a Maverick with a 351, with no clearance issues. They appear to be between shorty and long tube headers, they also go from 1 3/4 to 1 7/8 about half way down the tubes, they are built to be a lot more narrow than the 6901,S. Looks like they could actually give some much needed room. Anyone ever tried them on a 302 motor? anyone ever heard of them?
