The PB1803 oval port heads come with fully CNC combustion chambers, critical bowl blending under the intake and exhaust valves to produce an amazing 490/328 cfm air flow @ .900″ lift with a 413cc port volume not a 425cc port. That means the air flow is faster and can charge the cylinder with more air and fuel for more power than most other fully cnc ported versions! Some engines just don’t need the full CNC BP PB 1803 because of too much air flow, N2O or they want to finish the port their selves. So we offer both packages for your choice and still produces great power increases over standard BBC valve angles. Brodix heads have the best push rod clearance in the business. No machining the castings after the heads are on to get the push rods in without interference.
