Let me ask this. Are you going to port and polish your intake manifold? If yes then for sure do the exhaust. You want want less resistence on the exit then on the intake. Just a rule of thumb with blown motors.Thats why you find long duration on the exhaust side of camshafts, to make sure all the spent gases gets out.
