CYLINDER HEAD WORK

Face it, almost all production cylinder heads can be made to flow better.  From the finish to the shape of the port, it all plays a part in how well the gasses flow into and out of the combustion chamber. It's not even necessary to have a high performance engine to benefit from the gains of a better flowing head.  NO exotic claims here, just simply the best bang for the buck.  Head work offered by N-R Performance consists of matching the ports to their respective manifolds, blending in the valve seats and valve guides with the port itself and, finishing each port and combustion chamber for better flow.

No magic wands, just the hand finish the factory can't do.

                 Intake port ready for finish.                 Exhaust port ready for finish.

Combustion Chamber ready for polish. Blue dye around seats is from valve lapping.

Head work as described above
