i have run across a deal for some skunk2 valves and debating on to get them or not. i will port and polish the head but is it worth going overbore to get overbore valves? i am getting them new for around 200. should i get them and its no big or should i get overbore? i plan to hit 350whp with the t3/t4 50trim .48 when its on my built motor. what do u all think on this? thanks all comments are greatly appreciated
