Place the high-performance intake manifold gaskets and exhaust gaskets in place and secure them with the bolts or nuts. Use a scribe to mark the areas to be matched. Now remove the gaskets and use the rolls of 80-grit sandpaper screwed onto the mandrel attached to the high-speed air-operated grinder to match the ports to the gaskets.

Use water while sanding the manifold then with 1200-grit sandpaper. Rinse the manifold and allow it to dry completely. Place the buffing pad on the drill.

Pour aluminum polish onto the manifold and use the drill and buffing pad to apply the polish. Intake Head Porting - Precision Intake Flow Ports need to be matched up so the transition from manifold to head isinvisible to the airfuel charge as it travels toward the intake valve. 4 Exhaust port and bowl polishing.

5 Combustion chamber polishing. 6 Intake manifold port matching. Five of these six tasks reduce restriction in the intake and exhaust tracts.

The remaining step polishing the combustion chambers inhibits carbon build-up decreasing an engines tendency to detonate or knock under heavy load. We here at Mirror Finish Polishing can Polish any Intake Manifold you might have whether it is Aluminum Steel or any other metal.

Its OK for flow if the port running is smaller in diameter than the exhaust manifold but not vice versa.
