so what valves should i run? i am not sure. havent had a chance to call brad up and talk to him either. so trying to get some inputs before i order all my parts and send to him. also another question. anybody think dry sump is fine for daily driving?

You need to ask your porter which valves he recommends with his port work.The shape of the valve affects flow.The stock valves have a great shape but every one has their preference.He may also recommend a size change in the valve.Take the time to make the call.A drysump should be fine for a daily driver.
