    Victor Pro-Port Raw Big Block Chevy Cylinder Heads for Professional Head Porters

    Edelbrock has designed the perfect head for a professional cylinder head porter and engine builder. These heads are unported versions of Edelbrock's race-winning Victor series heads. The Victor Pro-Port cylinder heads are a semi-finished casting that gives the professional cylinder head porter the ideal starting point to design their own hand or CNC port. To allow for custom porting, the ports and chambers are un-machined and manganese-bronze valve guides and valve seats are available with certain heads. The Pro-Port heads are cast right here in the USA at Edelbrock's state-of-the-art facility.


    NOTE: These heads can not be used without professional head preparation.

    HIP Process HIGH-TECH PROCESS DELIVERS STRONGER CASTINGS
    Heads are available with a technique called Hot Isostatic Pressing (HIP). This aerospace process takes raw castings up to 900° F in a pressurized chamber (up to 30,000 psi) and compresses the casting. The results: an incredibly strong, super dense sand casting that has three times the fatigue life and nearly the consistency of billet aluminum.
