BTR BTR-CVH1C-6A Details

The BTR Canted Valve LS Cylinder Head LS1 6-Bolt CNC Ported Assembled is a high-performance cylinder head engineered to maximize airflow and power production in LS-based engine builds. Developed through extensive cylinder head design and testing, this innovative canted-valve configuration improves valve positioning and unshrouding to enhance airflow efficiency. The LS1-style cathedral intake ports are CNC finished to 250cc, while the combustion chambers are machined to 63cc for consistent combustion and performance.

The exclusive BTR canted-valve design utilizes an 11-degree intake angle and 13-degree exhaust angle, enabling intake flow figures exceeding 360 CFM at .650-inch lift when paired with BTR's port program. Each cylinder head is fully assembled with OEM-style LT1 2.125-inch hollow-stem intake valves, 1.590-inch exhaust valves, and BTR .660-inch lift Platinum valve springs. Designed to work with OEM-style LS1 pedestal rockers, intake manifolds, exhaust manifolds, and valve covers, these heads offer exceptional performance while maintaining compatibility with many factory-style components.

Constructed with a robust .750-inch-thick deck and a popular 6-bolt configuration, this cylinder head is built to withstand the demands of naturally aspirated and boosted applications alike. Sold individually, the head arrives fully machined, CNC ported, and ready for installation on serious street and racing engines.
