I just replaced my old 4-1 one piece header because the bottom 2 runners were dented to hell. My teg is riding on H&R race springs so ground clearance is low. So this time around I wanted to go with a 4-2-1 header. Found a new neuspeed 4-2-1 2 piece for a good price. Everything went well until I tried to mount it to the block. One of the 3 bolts that mounted the primary to the secondary header was hitting the block. So I ended up having to cut about 1'' out of the webbing of the block. I might have expected this out of an ebay brand header but I would have thought that neuspeed engineering would have been better than this. Anyone else have this problem?
