Small Block Chevy 283 305 327 350 400 Black Lakester Lake Headers Street Rod SBC. Small Block Chevy 283 305 350 400 Black Lakester Lake Headers Street Rod SBC. This listing is for a brand new set of Black Lakester Headers. These exposed small block Chevy headers work great on rods without hoods, but we’ve also seen them peeking through carefully trimmed hood sides. Each lakester header has a flange so you can connect it to a muffled under-car exhaust when the end plate is on. There might be some visual imperfections (none of which hinder the performance of the headers). With standard or Vortec heads including D-port ZZ-4 style heads (not LT-1). Flange Style: Round Port. Collector Diameter: 3.5. 1-5/8″ primary Includes flange to connect 2″ exhaust pipe. Removable end plates allow you to run open headers with ease. Includes gaskets and mounting hardware. Please remember that header fitment is not always perfect and while 95% of the time these headers fit fine, occasionally slight modification is needed for that perfect fit.
