Ping's are best done by Ping if you need more than a degree or so of adjustment. They also paint the dot. Usually pretty cheap per club and they turn them around quickly. That said, what can't be changed cheaply are the shafts; you're gonna want to make sure those are a decent fit before you hit them and turn new clubs into used clubs
So I'd go to PGA SS or wherever they were purchased, ask for some help in determining lie angle and shafts for the 430s which they'll have you hit demos, then you can react from there. If the shafts you have are not a fit, I'd ask to see what they can do on a new for new trade (or exchange using who bought them for you). If the shafts are fine, I would probably just have Ping do the lie angles. It is important to get the lie angle right.
