Frank, I have a set of SS Kooks 1 7/8 headers that are made for 1st gen camaros with LS engines.... I had to modify the Pasenger side to clear the frame.....What I did was cut 1/4 inch from each runner that are welded at the Header Flange....I angle the header so it clears the frame and then I tack them in place....My headers will clear an Art Morrison,Wayne Due and Speedtech Frames.Who knows they might just be a direct fit and you will save alot $$$
If shipping was not so much, I would ship them to you for testing.
