318 head porting for the average joe

Why would you keep everything the same? Everything is in the combination. I can get smaller chambers with 360 heads than your stock 318 heads. Power is airflow through the engine. If you cannot port heads, you run the best heads you can for the buck. And I am not telling you to get and set up 360 heads for your car. I already said I would leave it alone as long as it is running well.
