    Bolt-On 100+HP Over Cast Iron Heads!
    15° Intake & Exhaust Valve Angles

    The Brodix Big Block Mopar B1 BS Series is available in two different versions, out-of-the-box and 100% CNC ported. These versions offer a 90-120hp gain over their cast iron competitors. The B1 BS Series is the out-of-the-box version that has bowls blended, intake ports matched, and a multi-angle valve job. The STS B1 BS Series is 100% CNC ported version that's completely ported and contoured to assure maximum airflow and velocity. The B1 BS is absolutely the best buy for Mopar racers who would like to replace their cast iron heads and add horsepower. The B1 BS Series use some special parts such as rockers, head studs, and longer pushrods.

    The B1 MO Series is designed for the serious Chrysler ''B'' big block racers and is easily capable of flowing over 400 cfm. The B1 MO Series requires some special parts such as pistons, rocker system, intake manifold, and valve covers. This head uses standard headers and a ''B'' block. A moved centerline (MC) version is also available by special order. All heads in the B1 Series utilize a thick deck that is compatible with nitrous.

    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 ductile iron valve seats installed. Sold Individually, 1/pkg.
