Brodix "Big Duke" 18 Degree Oval Port Aluminum Chev BB Head
The PB 1803 head features an oval port intake runner and uses all standard components for the 18 degree Pro Stock head excluding the manifold. Brodix contacted the best head porters in the business to incorporate their porting design into a 100% CNC ported masterpiece. The PB 1803 offers a 410 cc intake port that allows maximum air flow. The PB 1803 is an excellent choice when looking for serious torque and horsepower. Note: These heads require special pistons, valve covers, head studs, rockers, and intake manifold. Assemblies include 2.450/1.860 stainless steel valves, 1.625" roller springs, 10 degree titanium retainers, and machined locks.
