just do it..........its a stock 350, your not gonna rocket anywhere with stock heads, besides a port and polish makes better performace, when you add more air and fuel to the mix, so think about a small turbo or even a small supercharger, but just do the port and polish for shits and giggles, so later on you can add more air and fuel.
