Product Details

The Edelbrock 60859 Performer Cylinder Head is engineered specifically for 1987-1995 Small Block Chevy 5.7L engines with Throttle Body Injection (TBI) or Tuned Port Injection (TPI) systems that were originally equipped with center bolt valve covers. This high-quality aluminum cylinder head delivers improved airflow and performance for street-driven vehicles while maintaining 50-state emissions compliance.

Key Features:

  • Designed for center bolt valve cover applications with proper compatibility for factory covers
  • Intake bolt pattern features the correct 73-degree angle on the two center bolts for 1987-1995 applications
  • Maintains stock compression ratio when paired with the recommended head gasket
  • Premium intake and exhaust valves with high-quality valve springs for reliable performance
  • 50-state street legal for hassle-free emissions compliance
  • Ideal for street performance builds, daily drivers, street rods, and muscle car restorations

This Performer cylinder head provides noticeable seat-of-the-pants performance gains over stock heads while retaining excellent street manners and drivability. Perfect for enthusiasts seeking reliable power improvements without sacrificing emissions legality or everyday usability.
