Good To Know

Q: Do these heads come assembled with valves? A: No, these are bare castings and require valves, springs, retainers, and seals to be purchased separately. Machine work such as valve job and surfacing may be needed before assembly.

Q: Will these work with my existing intake manifold? A: Intake compatibility depends on the intake port configuration, so verify the manifold matches these heads before ordering. Always confirm application by engine code and build spec.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
