Valve guide question

So after playing around, if I put my finger over the top of the guide and pull out the valve at a good speed they make a pretty loud pop. I may not do anything to them right away now. I talked to a machine shop I have used in the past on the AL head in my daily driver and they said they don't do liners and said for new bronze guides it was $125 for labor, plus guides, and $98 for vg on both heads. I was talking to a guy local, that races a Dart on the strip, and he said the in the new guides would be better for the long run from his experience. Right now I think I will run the guides as is then later down the road put in new guides and valves if necessary.
