Edelbrock Jeep 4.0L I6 Victor CNC Cylinder Head

Overview

This Victor CNC cylinder head for Jeep 4.0L inline-six engines is a fully CNC-ported version of the popular 50169 Performer cylinder head Edelbrock has been producing for the past 19 years. The head features a 182 cc intake port, a 77 cc exhaust port, and a 55 cc combustion chambers. As an additional improvement the Victor CNC has a valve job to match up with the COMP Cams LS-style 8 mm valvetrain. Utilizing the LS-style valves opens a larger variety of valve spring combinations to fit any camshaft profile. These heads are manufactured with premium materials and machined to the industry’s tightest tolerances. Features include ductile-iron valve seats and fully CNC-machined ports for maximum airflow. The premium manganese bronze valve guides withstand long wear with emphasis placed on holding precision tolerances on valve seat concentricity to securely seal the valves, eliminate leak down, and increase cylinder pressures during engine operation.
