    Cylinder Heads for Serious Race Applications!
    18° Intake & Exhaust Valve Angles

    This -18C series cylinder head has an 18-degree valve angle that works well on dirt late model or serious drag racing applications. This head has special valve centerlines and dowel location requiring special components. Interlocking valve seats are installed along with replaceable phosphorous bronze guides. The combustion chambers may be angle machined down to the mid 40cc range without weakening the deck surface. The -18C has two exhaust bolt patterns available and a 5° intake face requiring a special intake manifold and components. 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. The industry standard has been taken to the next level with modernized CNC porting. 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 interlocking valve seats. Sold in Pairs. !
