BTR CANTED VALVE LS CYLINDER HEAD - LS1 6 BOLT - PORTERS CASTING - - Brian Tooley Racing - BTR-CVH1P-6U

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!and#x0D; and#x0D; There-™s no other low-cost premium cast all-American canted-valve LS cylinder head on the market! By rotating the intake 5 degrees and exhaust 3 degrees 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.; BTR exclusive canted-valve design allows for maximum valve unshrouding and sizing - Cathedral fits a 3.780" bore LS3 style fits a 3.820" bore!and#x0D; 11° intake (5° canted) and 13° exhaust (3° canted)and#x0D; Cast in Iowa - Designed tested machined & sold in Kentucky!and#x0D; Intake flow - Over 360 CFM at .650- when used with BTR-™s port program!and#x0D; Uses OEM LT1 2.125- steel hollow-stem intake and 1.590- steel exhaust valvesand#x0D; LT4 Ti intake and L8T Inconelâ„¢ exhaust valves can also be used with lash capsand#x0D; Superior OEM-type powdered metal guidesand#x0D; Utilizes OEM-style straight LS1 pedestal rockers OEM-style intake & exhaust manifolds and LS-style valve coversand#x0D; Uses Gen V LT style long reach spark plugs and valve spring kits up to 1.350- O.D. springand#x0D; Clears 3/8- pushrods -“ Typical length intake 7.925-8.025- & exhaust 7.900-8.000-and#x0D; Extra-thick .750- boost-friendly deck in popular -œ6-bolt- configurationand#x0D; BTR / Wiseco Canted-Valve specific pistons available for most popular LS applicationsand#x0D; Multiple Patents Pending!and#x0D; and#x0D; and#x0D; This cylinder head ships partially machined with finished valve guides and unfinished valve seats installed for cylinder head porters to customize for their application.
