I am thinking about changing the headers on my 1972 Chevelle. The car has a LS-6 454 motor. I currently have Hooker Super Competition 2" tubes with 3 1/2" collectors. I'm looking to see if anyone, on the Board, has installed the 2 1/8" style on a 1968 to 1972 Chevelle. Those have the "over the frame" tube. Just wondering if you have to cut the fenderwells or if they clear everything. If cutting is involved, then they are not for me. My buddies are telling me to put cast iron manifolds on.
