ROX Heads – A Serious Casting for All Out Competition

Engineered for all out competition, Edelbrock’s ROX Pro-Port Raw cylinder head, #777669, offers a high quality casting that is ideal for extreme circle track and drag racing applications.

The all-new Victor ROX Pro-Port Raw cylinder head is designed for serious dirt track and drag racing competition applications. It has been cast with extra material in the intake ports, exhaust ports and combustion chambers to allow for application specific professional CNC or hand porting. It also features raised exhaust ports to improve flow efficiency and the deck includes extra material to allow fine tuning of the combustion chamber. This head is designed to accept GM SB2 style valve covers. The ROX Pro-Port Raw is the first cylinder head to market that is exclusively designed for engine blocks with 4.5″ bore spacing.

The Edelbrock Victor ROX Pro-Port Raw is treated to a Hot Isostatic Pressing (HIP) process to ensure the finest and most durable casting quality possible. HIP processing is a forming process that combines heat and pressure to consolidate the metal and press out any gaseous material. The end result is a dense casting, comparable to billet material. Resulting in minimal distortion when used in forced induction and extreme duty applications.
