Edelbrock Victor CNC® LS7 Cylinder Heads are one of the first aftermarket high-performance LS-style heads to feature a raised intake runner design that fits both stock and aftermarket LS7 intake manifolds and valvetrain setups. The raised runner and rolled valve angle increase overall flow capability, while an improved water jacket design improves thermal conductivity. These premium 110 BHN 355-T6 aluminum alloy cylinder heads (#77699) are designed with a 12-degree valve angle and unique 307 cc .220" raised intake runners to provide a better line of sight into the 69 cc chambers and allow for an improved short turn. The exhaust ports are also raised .100" to allow the use of stock and aftermarket manifolds, while the .400" raised rail works with aftermarket rockers. The 100-percent CNC-ported runners and combustion chambers optimize volume, atomization, and velocity. The 6-bolt design increases clamping capacity and greatly improves head gasket retention in high-horsepower and boosted applications in small and large cubic inch, hardcore street applications. It also makes it compatible with the advanced Edelbrock LS Race, GM LSX 6-bolt, and OEM 4-bolt blocks. Built to withstand race conditions, the .750"-thick deck surface and a reinforced solid rocker rail increase integrity, rigidity, and stability. The copper-infused powder metal seats received a 2.200" intake and 1.615" exhaust valve job. The heads are sold bare, but we recommend COMP shaft mount rocker system (#1523CPG), valves, and springs, or if you want to use single rockers like #1479-16, you will need our LS7 rocker stands (#54520-2).
