For applications ranging from bullet proof street cars to 2000+ HP monster small blocks, the Brodix LS7 is an ideal choice due to its superior deck structure, easily repairable A‐356 virgin aluminum alloy, and super low porosity casting. Like all of our heads, the FRH BR7 is not a reworked cylinder head but fully developed from scratch using a raw casting.
The intake ports, exhaust ports, and combustion chambers are 100% CNC machined on our state‐of‐the‐art 5‐Axis CNC. When combined with a valve job designed to match the characteristics of the ports perfectly, the end result is a cylinder head that simply makes more power as have been verified on the dyno and at the track! This casting is available in an optional 6‐bolt configuration and can accommodate either a small hydraulic spring setup or a large OD solid roller.
