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 BB-3 XTRA CNC ported oval ports are available in three port volumes: 351 cc, 365 cc and 371 cc. This wide range of port volumes allows the oval port to dominate virtually any engine combination available. Port shape, port velocity, and the latest technology have propelled these cylinder heads to the top of their class.
