Speedway Motors 9300550H Details

Nostalgia-style street rods are hotter than ever, and nothing gives your vintage rod that authentic dry lakes competition look like a set of lakester headers. The exposed small block Chevy lakester header works great on rods without hoods, but we’ve also seen them peeking through carefully trimmed hood sides. The headers have flanges so you can connect them to a muffled under-car exhaust when the endplates are on. These ceramic coated headers feature superior performance and durability.

  • Fits 265-400 c.i. with standard or Vortec heads including D-port ZZ-4 style heads (not LT-1) 
  • Includes flange to connect 2-1/2” exhaust pipe
  • Removable end plates allow you to run open headers with ease
  • Includes gaskets and mounting hardware

NOTE: Turn-outs NOT included. Headers come with end plates (turnouts sold separately).
