Description:
Sportsman racers need reliable parts that will get them through the entire race season. Edelbrock Victor DR-17 Pro-Port raw cylinder heads are designed to give consistent performance in big block Chevys. These new-wave heads are based on the 24 degree Victor Gen II raw design, but feature 17 degree intake valve angles for improved efficiency and combustion, and a slight adjustment in location for better flow.

Edelbrock uses a pressurized chamber and aerospace process called Hot Isostatic Pressing to compress castings at nearly 900 degrees F and 30,000 psi to give them nearly three times the average fatigue life, wicked strength, extreme density, and near billet aluminum consistency. DR17 Pro Port heads are cast with enough wall thickness for CNC-machining to various port dimensions, and will allow most CNC port shapes, sizes, and locations. Be ready to rumble next season with Edelbrock Victor DR-17 Pro-Port raw cylinder heads.

Additional features include:

* Raised intake port + 0.400 in.
* Taller valve cover rails
* Revised water jackets for maximum-effort port designs
* Generally, seats and manganese-bronze valve guides are included, but not installed
* Exhaust port location raised + 0.600 in.
* Shaft rocker system required
* Tall deck applications require the use of spacers

** Professional cylinder head preparation is required for use.
