  • Specifications:

    Manufacturer's Part Number:

    The same technology that dominates NASCAR and the NHRA is available from Chevrolet Performance to the public for Saturday night late models and serious drag cars. Sold individually, these aluminum in-line valve cylinder heads have thicker deck material, thicker manifold flange areas, powerful combustion chambers, and high-velocity air passages.

    Drag racers in NHRA's Competition Eliminator Class want big compression, lots of RPM, and cylinder heads that deliver maximum power at the crack of the throttle. Paired with the correct short block, valvetrain, and intake, these racing heads are exactly what small displacement drag racers need. Chevrolet engineers have dramatically altered this cylinder head's valve architecture to improve flow and maximize efficiency.

    Technical Notes
  • Requires Longer-than-Stock Valves
  • Designed for 4.000 to 4.155 Cylinder Bores
  • Revised Port Locations for Superior Flow above 0.600 Valve Lift
