Default Replace Int/Exh Valves

Hello fellow Volvo lover,
I need some advice. Here is a short story on what happened. had a exhaust cam gear seal leak, I bought a new cam gear with the seal. I used the tool to hold the cams in place. I did everything by the book, but I guess not cuz on my 5th try I lost compression. Skip forward I removed Head bend most valves and ding e piston tops see pictures.

I am looking for new Intake/Exhaust valves. Price from $8-64 /valve. which one to get? I cannot afford $64/valve but I need to know what is difference most of them say OEM or OES.
ADVICE 2--
See pictures of piston tops do i have to replace, I had a mechanic look at them and he said no problem i can use them but i would like 2nd opinion.
thank you

No need to replace the pistons. Just smooth out the edges around the indents so there are no hot spots developing.
