I made pulls with a 3x14 w /extreme lid, 4X14 w/extreme lid, both with steel top and the 3x9 with steel top. In my application, the extreme lid did NOT hurt performance, it helped when running the 14X3 slightly BUT remember, I am running efi so no fuel or air bleeds to get disrupted or anything either which is what I hear happens, Smitty
