These unported versions of race-winning Edelbrock Victor Series CNC heads are designed specifically for the professional cylinder head porter and engine builder. Like all other Edelbrock Cylinder heads, Pro-Port units are also casted in the USA at the state-of-the-art Edelbrock Foundry with extra-thick walls to allow for custom CNC porting. In most cases, seats and manganese-bronze valve guides are included, yet not installed. Please note: These heads can not be used without professional head preparation.
