Headers

Hi all. Has anyone used Dougs headers for a swap? I'm putting a 2004 5.7 in a 70 Belvedere wagon, I know its not an A body but didn't get any info on the B body forum. Found a brand new set for $325 for this swap but don't know anything about how well they will fit OR not. TTI are the most popular, but pricy for me right now.

Thanks Darrell
