Speedway Motors 9300114C Details

Many rodders are looking to install Chevy’s powerful and efficient LS1 / LS6 Small Block V8 in their street rods, customs and classic trucks. These shorty headers can make those installations easier in a variety of applications, and help produce more power as well.

An oxygen sensor bung is included with these block hugger headers, but not installed, for those who want to keep the engine’s electronic fuel injection. Includes bolts, gaskets, and reducers.

Chrome Warning: Due to a revised chroming process brought on by recent EPA regulations and high labor costs, today's chrome is not the quality of days gone by. Be Aware: Exhaust components which are chrome plated are now much more susceptible to blueing, blistering, peeling & corrosion. No warranty or returns on chrome exhaust items once them have been installed.

Not legal for sale or use in California on pollution controlled vehicles


  1. 1997 and newer Chevy Gen III small block LS1 / LS6 
  2. Note: To allow maximum clearance, these headers require the use of our 916-18016 motor mount adapters. They will not fit when using the OEM LS-Series motor mounts.
