BTR CV Canted Valve LS Cylinder Heads

What happens when two of the most respected names in cylinder head development come together? You get a true game-changer. The BTR CV (Canted Valve) LS Cylinder Head combines decades of innovation from Rick Smith and Brian Tooley to deliver next-level airflow, efficiency, and power potential for serious LS builds.

By incorporating NASCAR-proven canted valve technology—rotating the intake valve 5° and exhaust 3°—these heads dramatically improve valve unshrouding and airflow, achieving 360+ CFM at just .650” lift with BTR’s in-house port program. The result? More power, better efficiency, and a clear advantage over traditional inline valve LS heads.

Designed to bridge performance and practicality, these heads retain compatibility with common LS components like LS1 pedestal rockers, valve covers, and intake/exhaust manifolds, while utilizing modern Gen V LT valves, spark plugs, and spring packages. This hybrid approach makes building a high-performance setup easier without sacrificing cutting-edge performance.

Built with a thick .750” deck and 6-bolt configuration, these heads are ready for high-compression and boosted applications alike. Whether you’re building a street car or a competitive race setup, the BTR CV heads deliver serious capability at a price point unmatched in the canted-valve market.

⚠️ Note: These are porter’s castings and are not intended for out-of-the-box use. Final porting, chamber work, valve seat machining, and decking are required.
