BRODIX BB-3 XTRA SERIES 24 DEGREE CYLINDER HEADS 2030001-2038115

BRODIX® Introduces the BB-3 XTRA O™

BRODIX now has a 24º oval as-cast big block head.  The BB-3 XTRA O™ has a newly designed 335 cc oval intake port and CNC ported combustion chambers.  The head flows 420 cfm and comes standard with 119 cc combustion chambers, 2.350/1.880 valves, CNC blended bowls, CNC matched ports, and honed guides.  Standard rockers may be used with this head.  The “Oval 335” is the perfect fit for the budget-minded racer looking for the latest in cylinder head technology.

The BRODIX BB-3 XTRA has taken the conventional big block to the next level. These cylinder heads feature a valve angle that is
rolled two degrees. The -3 XTRA is available in a rectangular-shaped or oval-shaped intake port configuration, and both are offered in
an out-of-the box version or completely CNC ported. The out-of-the-box versions come standard with CNC ported 119 cc combustion
chambers, CNC bowls blended and ports matched, and flow over 390 cfm. The BB-3 XTRA CNC ported version is available in two
port volumes, 366 cc and 380 cc. The 380 cc version flows over 440 cfm. The BB-3 XTRA CNC ported oval ports are available in three port volumes: 332 cc, 351 cc, and 365 cc. This wide range of port volumes allows the oval port to compliment virtually any engine combination available. Port shape, port velocity, and the latest technology havepropelled these cylinder heads to the top of
their class.
