Brodix -12 W B MC Series Cylinder Heads 70/125 Valve Spacing

Excellent Cylinder Head for Nitrous Builds!
15° Intake & Exhaust Valve Angles

In the mid 1980's, Brosix was the first company to offer a ''rolled over'' valve angle cylinder head. Since then, the -12 series cylinder head has won thousands of drag race, late model and sprint car races...AND is still winning races today. Brodix has taken this design even further by adding raised intake ports, specially shaped intake and exhaust ports, some choices of valve spacings, and more efficient combustion chambers. The -12 series cylinder head is available in several port sizes to fulfill your needs. Some heads are available milled and drilled for down nozzle injection. 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 installed.
