Description

Precision Race Components presents a new cylinder head casting suitable for 4.8/5.3/LS1/LS2 engines. These are designed to match the stock valve angle of LS engines and have thicker decks, ensuring compatibility with stock piston-to-valve setups.

Origin:

  • Cast, Machined, and Produced entirely in the USA.

Key Features:

  • 220cc Intake Runners
  • 84cc Exhaust Runners
  • Bolt-on design with little to no pushrod length adjustment
  • TSP .660 Spring Kit with PAC Valve Springs & Titanium Retainers
  • 64cc precision-machined chambers
  • CHE Bronze Guides
  • 2.045″ Stainless Intake Valves and 1.600″ Stainless Exhaust Valves
  • Compatible with factory rockers
  • Extra thick deck surfaces for enhanced power

This new 220cc cylinder head is a superior 15-degree LS cathedral head, serving as a robust replacement for LS1/LS6/LS2 factory castings. It’s the ideal choice for those seeking a high-quality aftermarket option without changing existing components.
