    4.500'' Bore Spacing!
    15°/4° Intake & 6°/4° Exhaust Valve Angles

    The introduction of the PB 5000 series heads blows the 5.0-inch bore spacing market wide open. These masterpieces are by far the most user-friendly heads in their class. These heads offer several features that include: 15° valve angle, raised oval-shaped intake ports, and specially designed combustion chambers that are nitrous-friendly. PB 5000 series heads require special pistons, valve covers, head studs, shaft mounted rocker arms, headers and intake manifold.
    Every casting is poured from A-356 virgin aluminum and tested before Brodix utilizes their in-house processes such as finish machining and heat treating to assure that you receive the best products for your hard-earned money. Other features include a thick deck surface that is compatible with nitrous, drilled and tapped holes on the ends for standard drive accessories, phosphorous bronze valve guides and copper valve seats installed. Sold Individually, 1/pkg. Made in the USA!
