These manifolds are designed for maximum airflow and power with a 4500 Dominator-style carburetor flange. Engineered to fit most 24-degree style race cylinder heads, RHS took additional efforts to ensure excellent port matching when paired with RHS Big Block Chevrolet cylinder heads. These manifolds are available in both carb and EFI versions and offer excellent performance for drag racing and marine applications.Featuring a single-plane design, they utilize individual runner dividers for excellent throttle response and exceptional torque. Available for both short and tall deck blocks, all versions utilize a standard BBC distributor – there is no need for a slip collar distributor or special distributor for tall deck engines. They feature auxiliary water ports, an integral water crossover and dual distributor hold-down pads. Ports for water lines are also provided at all four corners. RHS also teamed up with sister brand FAST to create a revolutionary EFI version of the manifold that features port angle optimized injector bung mounting and machining, which angles the injectors to point directly at the valve. In addition, the EFI manifolds feature integral sensor mounting points to improving function, fitment and packaging.
