Product Details

The Hooker 2551-2HKR RacingHeart Street Stock Headers are engineered for Small Block Chevy engines in street stock circle track applications. Constructed from durable 409 stainless steel with a natural finish, these long-tube headers deliver enhanced exhaust flow and performance for classic GM muscle cars.

Key Features:

  • 1-3/4 inch mandrel-bent primary tubes with 3 inch collectors for optimized exhaust velocity
  • 3/8 inch thick flanges to prevent warping and ensure maximum sealing surface
  • Merge spears in collectors for increased exhaust velocity and scavenging
  • Fits both straight and angle plug heads
  • Includes gaskets and hardware for complete installation

Hooker Headers are engineered to increase horsepower and torque while improving throttle response. The mandrel-bent tubing ensures smooth exhaust flow with minimal restriction, while the merged collector design maximizes scavenging efficiency. These headers are designed for racing use only on vehicles not registered for street use.

Note: Requires short oil filter. Will not clear A/C box or stock manual clutch linkage ball. Engine must be in stock location.
