i'm about the squeeze my 512 Stage 6 headed beast back into my 'cuda. Hooker comp headers miss everything when bolted up but you have to fit at the same time as the engine. i'm thinking of cutting off the collector & using a slip on version & cutting the flange & make each side a 3 tube + collector piece. I hoping then i can move just a single tube to give access to the starter & ease of header flange gasket replacement.
