This is a pair of finished heads with the valves fitted to the guides, a valve job & seat work along with our Stage 3 level of CNC porting work. These are fully CNC'd including the bowls. This does not include the spring kit.
These heads feature our new "Fat Flow" porting service to achieve excellent flow to the cylinder. The chambers are all fully ported for more flow at all lifts and it inlcudes our special Hughes Engines "Wet Flow" valve job. The heads comes with 2.20" intake valves and 1.81" exhaust valves.
CNC porting of the heads will increase the overall chamber size. If you need the heads milled to a certain cc
or are trying to achieve a specific compression ratio, let us know and we can quote you a price on milling.
NOTE: The Edelbrock Victor heads have heli-coils in the rocker hold down stands and in the exhaust bolt holes. The Pro Comp heads do not have heli-coils in any of the bolt holes.
