Hey man,
All I would do is gasket match the intake to the cylinder head, you don't want to polish it because you need to keep up boundary layer agitation to keep the fuel in suspension so that it doesn't puddle, keeping the fuel atomized is one of the keys to complete combustion, the smaller the droplets, the less time it takes to burn the gases in the combustion chamber, thereby avoiding detonatin problems.
word up.
