port and polish is an old muscle car engine builder job. however ther are gains to be made. what is done is the port for the intake and exhaust is opended and polished so the air flows smoothly and fast. that is the basics of it. the reality is that it is very subjective and and it is a skill that takes time to get right and not all engines respond well to this. to large and your bottom end torque will suffer, to smooth an exhaust and you loose scavaging... look into a engine builders book at borders or your local book store and review that before you decide, all engines are basicly the same for building so the hot rod engine builders books explain nicley what is being done.:thumbup:
