EngineQuest Cast Iron Cylinder Head

The EngineQuest EQ-CH350I is the sole legal spec head option for small block Chevy-powered IMCA Sport Mods and Hobby Stocks, serving as a direct replacement for OEM Chevy 350 heads. This bare casting is constructed from durable cast iron and features 167cc intake ports and 76cc combustion chambers. Designed for performance, the EQ-CH350I includes 1.94" intake and 1.50" exhaust valves, a superior port finish for increased airflow, and redesigned water passages for improved cooling. It also boasts thicker decks and a professional three-angle valve job. The head is serial numbered, includes the IMCA logo, and is sold individually. This cylinder head is compatible with Small Block Chevy engines and utilizes a straight plug design. While the bare casting is sold individually, a complete assembled version is also available, which includes stainless steel valves, performance valve springs, retainers, keepers, and 3/8" screw-in studs.
