Description

The LS EQ-CH364BA is an assembled pair of GM LS cylinder heads, replacing casting numbers 243/799. Made from high-grade aluminum, these heads feature a thicker deck for increased strength and an improved design to resist cracking. They offer superior port finish for better flow and a redesigned water flow for enhanced thermal conductivity.

These heads include 100% new OE type valves, seals, valve springs, and retainers. The combustion chambers are swimming-pool shaped, and they are intended for use with low-lift truck valvesprings, with a 69cc volume per cylinder and Cathedral Port style.
