If you are looking for raw horsepower in a cylinder head, here is your answer. The PB 2005 is simply the best of the best. This head is offered in two versions, out-of-the-box and completely CNC ported. The out-of-the-box version flows an unbelievable 535 cfm. CNC ported, the PB 2005 flows over 560 cfm; this is unmatched by any other 4.840 bore spacing head. Valve sizes include 2.520 intake valves and 1.860 exhaust valves, both with a 55º seat angle. All of this horsepower would go to waste without the strong castings BRODIX provides. As usual, the PB 2005 offers the standard qualities of solid phosphorous guides, gorilla valve seats, extra thick deck, and the best aluminum in the business (A-356 Virgin Aluminum)
