Anything on the intake side you want a satin finish as it promotes a boundary layer of fuel/air for better flow. Exhaust runners in the heads you want polished. Definitely a port match job but ONLY if you can make the MANIFOLD side the same as or a tad SMALLER than the head side. No lip facing the upstream side ! As your pattern, use the same brand /part number intake gasket as you will be using in the final assembly.
NEVERNEVERNEVER do ANY grinding on an assembled head (in the port matching process ) that you are NOT going to disassemble and CLEAN before re-installation.
