Product Details

The EngineQuest EQ-CH364CA is an assembled aluminum cylinder head with rectangle ports for Chevy LS engines. It is also sold as an LS rectangle port cylinder head or an assembled LS3-style head. Because it arrives assembled, the valvetrain components are already installed.

Key Features:

  • Rectangle port design
  • Assembled, with new OE-type valves, seals, valve springs and retainers
  • Made from high-grade aluminum
  • Thicker deck for added strength
  • Improved design to resist cracking
  • Superior port finish for increased flow
  • Water flow redesigned for greater thermal conductivity
  • Hardened exhaust seats
  • CNC machined guides and seats
  • 3-angle valve finish
  • 25-point quality check on every head

This head suits LS engine rebuilds and performance builds where an assembled rectangle port head is needed.
