Opinion on valve guide damage

Ok, I have been tearing into a complete 318 I picked up late last year. I have recently began disassembly and inspection and clean up.

The guy I got it from had the engine was in an ebody used as a daily driver with some track time. He left all the fluids in it for inspection as well. Anyway everything is in excellent condition until I tore down the heads and found that that there definately was previous work done on them, new valves, new springs and shimmed accordingly. Now the seals are hard and a couple broken, I figured normal.

Here is my problem... looks to have had new guides at sometime but looks as thought they have now been knurled and there is some damage. There was nothing in the oil pan so perhaps the damage was done my the machine shop used? And IMO there is too much slop in the guides now so new guides are in order. BUT should I bother with these heads now or is that taking a chance? I dont know I just havent seen this before so my thought is to just junk em. What do you think?

Both heads have a couple like this.

Thank you
