The EngineQuest EQ-CH364C is a pair of new, assembled LS3/L92 style cylinder heads engineered for Chevrolet vehicles. Manufactured from the highest grade aluminum, these heads are built to enhance the performance of V8 engines with displacements ranging from 6.0 to 6.2 liters. Each cylinder head features a port volume of 258 CC +/- 2cc and an intake port dimension of 2.559”. The valve setup includes an intake valve head diameter of 2.165” and an exhaust valve head diameter of 1.590”. The chamber volume is specified at 69 CC, with a test pressure of 28 psi per inch. These heads are designed as a direct replacement for casting numbers 364, 5364, 821, and 823. Designed for use between the years 2001-2014, these cylinder heads are compatible with Chevrolet and GMC vehicles. The EQ-CH364C offers an alternative rectangle port design, with an LS3-based configuration and an LS7 intake runner to promote increased airflow and potential power gains.
