These Edelbrock Victor Max Wedge big block Chrysler cylinder heads are designed for the serious race enthusiast. They are made of aluminum and feature raised intake and exhaust ports for improved flow characteristics. The raised valve cover rails eliminate any chance of leaking gaskets. Available with or without valves, the Edelbrock Victor Max Wedge big block Chrysler cylinder heads have reamed and semi-finished valve stem guides and no valve job. They require final guide sizing, valve seat finishing before installation, and special offset rocker arms for the intake side.
