DESCRIPTION
Edelbrock Victor As-Cast Small Block Chevrolet heads are for the professional cylinder head shop or engine builder . We
offer them in both Victor 23° and 18° versions. The as-cast ports have enough metal thickness to allow for hand or CNC porting to several
different sizes for various applications providing the versatility for whatever your design requirements may be. Manganese-bronze
replaceable guides and ductile iron seats included but are not installed. The proper valve seat insert installation will require machining
the seat insert bores to the press fit size of seats being used. Valve guide bores are machined to final size. Valve stem clearance needs
to be finished by reaming and honing guides to size.
Note: Parts listed below are included but NOT installed.
