Pair Of LS1 Header Flanges, Laser Cut 3/8" A36 Steel LS2 LS6 2.125" Port Size (!!!The hole size cut in the flange for the tube is 2.125"!!!). I have used these to build 2" and 2.125" primary tube header for LS1 engines. 

I have been taking long tube header that would fit standard small or big block in specific application and cutting them up and moving them around to fit LS1 heads. I have been told by several people that the small block ford headers out a fox body mustang have the exact same port spacing as the ls based engines and that they will fit many applications, but I have not tried this yet myself. Just need a set of  headers that fit your specific application with a SBC or a BBC, a little extra tube the same size as your primary tubes, saw of some sort, welder tig/mig, and about 20 hours with alot of patience and you can make you own headers for your LS1 project. Save your self $600-$1000 on buying headers, if they make them for your application. Please feel free to email me with any questions you might have. Check out my other auctions for other LS1, Street Rod, and Drag Racing Laser cut bracket.
