I finally got to test fit the new headers on my '66 Chevelle. The passenger side doesn't fit. I can't get the header to go foward enough to line up the bolt holes. The tubes curve down too soon and are hitting the frame.
These are my new headers:

They're 1.75"x3". My old 2"x3.5" Hookers cleared the frame fine. The only thing I think might not be right with my car is the motor mount brackets. (The brackets that go from the frame to motor mount.) I'm not sure if they're correct. I once heard they were different between the big and small blocks and I think I got mine from a small block car. Would this cause a problem with the headers fitting?

whoever told you that you needed to swap out Hookers for one of the cheapo brands should kicked in the groin.
