BRODIX 2148101 SONNY'S 14.5* HEADS

Brodix 2148101 14.5-Degree Sonny's/BRODIX Aluminum Cylinder Heads

Flows Over 535cfm Out-of-the-Box!
14.5°/4° Intake & 6°/4° Exhaust Valve Angles

 This head is offered in two versions, out-of-the-box and 100% completely CNC ported. The out-of-the-box version flows an unbelievable 535 cfm with just intake port matching, blended bowl and complete valve job. The STS-series is completely CNC-ported, the STS PB 2005 series 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 55° 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.


PB 2005 series heads require special pistons, valve covers, head studs, shaft mounted rocker arms, and intake manifold.
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. 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 copper valve seats installed. Sold Individually, 1/pkg. Made in the USA!
