BTR BTR-CVH3C-6A Details

The BTR Canted Valve LS Cylinder Head LS3 6-Bolt CNC Ported Assembled is a premium performance cylinder head engineered to maximize airflow and power potential for LS-based engines. Developed through extensive cylinder head research and port development, this innovative design incorporates canted valve technology that improves valve unshrouding and airflow efficiency. The LS3-style intake ports are CNC finished to 260cc, while the combustion chambers are CNC machined to 64cc for consistent performance and combustion characteristics.

Featuring an exclusive canted-valve configuration with an 11-degree intake valve angle and 13-degree exhaust valve angle, the head is capable of delivering over 370 CFM of intake airflow at .650-inch lift when used with BTR's port program. The head comes fully assembled with OEM LT1-style 2.125-inch hollow-stem intake valves, 1.590-inch exhaust valves, and BTR .660-inch lift Platinum valve springs. Designed for compatibility with OEM-style LS1 pedestal rockers, intake manifolds, exhaust manifolds, and valve covers, it offers easy integration into a wide range of LS performance builds.

Built with a thick .750-inch deck in a durable 6-bolt configuration, this cylinder head is well-suited for naturally aspirated, boosted, and high-performance street or racing applications. It is sold individually and arrives fully machined, CNC ported, and ready for final installation with a stock-style LS rocker setup.
