Pontiac V8 Victor Pro Port Cylinder Heads
Race-Only Casting — Victor Pro Port Cylinder Heads for Pontiac V8s
Victor Pro Port castings are the extreme end of the Pontiac head world. The intake port openings are raised and the intake flange is extended, the intake valves are moved away from the cylinder wall for better burn with oversize valves, and the casting carries a center water outlet, raised valve cover rails and an interlinked rocker stud pad for valvetrain stability.
Butler stocks the 11 degree valve angle Edelbrock Victor Pro Port as bare castings with guides and seats, and as a complete set CNC ported by BES to 430-440 cfm with titanium valves and retainers. Matching T&D competition shaft rockers are available for them.

More About Victor Pro Port Cylinder Heads
1. Read the Block Requirement Before Anything Else
This is not a head you fit to a factory Pontiac block. The requirement is printed on every listing for a reason.
| Aftermarket blocks only | For use on aftermarket blocks only. Recommended bore is 4.310" or larger, with 4.280" the minimum. |
| Valvetrain | Requires offset solid roller lifters and shaft rockers. The T&D 9036 competition shaft rocker assembly is the set built for the Butler/BES Victor head; specify the ratio. |
| Intake | Compatible manifolds are BOP, Polarwind or custom sheet metal. The raised port and extended flange are what rule the ordinary street intakes out. |
2. What the Casting Gives You
The Pro Port design changes the head in ways that matter well before you get to the flow number.
| Raised intake ports | The 11 degree 77849 casting has 1.25" raised intake ports and flange, with stock exhaust port location, so it still works with Victor series manifolds and Ram Air IV style headers. |
| Valve placement | The intake valves are moved away from the cylinder wall, which improves burn characteristics when larger than stock diameter valves are used. |
| Chamber and valves | 50-52cc combustion chamber, with 2.350" intake valve diameter on the BES ported set. |
| Casting details | Center water outlet for improved cooling, interlinked rocker stud pad with extra thread engagement, and raised valve cover rails and spring pads while retaining the stock bolt pattern. |
3. Bare Castings or Finished by BES
Two ways to buy the same casting, and they suit two different customers.
| Castings only | Two bare head castings with guides and seats, rated 1100+ HP capable. These must be completed by a professional head builder. |
| CNC ported complete | Ported by BES to 430-440 cfm and delivered complete with titanium valves, titanium retainers and PSI or PAC springs, also rated 1100+ HP capable. |
| Getting help | Optional Sedig chamber divider inserts with installation are available on the ported sets. Call with the block, the bore and the class you are running before you commit. |
A Victor Pro Port head only makes sense when the block, the valvetrain and the intake are being bought around it. If you are on an iron or standard aluminum Pontiac block, the wide port or 340 cfm round port program is where the money belongs instead.
