What happens when you combine two lifetimes of cylinder head research and development? The BTR CV cylinder head for LS! When you have a cylinder head casting legend like Rick Smith on board (Father of the Hi-Port, A460, Twisted Wedge and more!) and decades of Brian Tooley's porting & cylinder head flow bench experience, you end up with serious game-changing performance!

There’s no other low-cost premium cast all-American canted-valve LS cylinder head on the market! By rotating the intake 5° and exhaust 3°, we’ve seen over 360+ CFM of intake flow… at only .650” lift with our in-house port program! We put NASCAR-proven canted valve tech into the LS head and made it attainable. These heads use regular Gen 3 & 4 LS1 pedestal type rockers & bolts, valve covers & manifolding… and use Gen V LT valves, spark plugs and valve spring packages to make building them out EASY with OEM-compatible parts! If you have a street machine or a racing class that allows a canted valve head, this is the advantage you’ve been waiting for.

This cylinder head is sold as a pair and ships fully machined and CNC ported with finished valve guides and seats installed. LT1 type valves are installed to correct height with our .660" lift Platinum spring kit, ready for your stock type LS1 rocker arm setup, then bolt-on and go!
