7afe valves Options

[Livewire]

So I have a question for you guys. I got the head pulled off and got it prepped for the new head gasket but while I was carrying it over to the bench I tripped on a jumper cable and fell on my seat head landed in my lap safe and sound, but 6 of the valve buckets and shims fell out and onto the ground. I don’t have any gauges small enough to check the clearances, so what would be my best course of action to make sure I get the right bucket on the right valves? In addition, when looking at the underside of the head I found not one but two exhaust valves with a deep burnt edge (looks like someone took a nibble). I checked the seats and they’ll be perfect after they get lapped, seems like the oil burning made a protective layer around the seat and when the edge of the valve broke/burnt it didn’t cause any damage. Whew. Anyways, background out of the way, should I just order a full set of valves to be safe or can I get by buying a pair of dnj exhaust valves to replace them and be okay? Funds are getting a little low until I can start driving again, so I’d really like to spend as little money I can here after everything else I’ve bought to get it running, and the other exhaust valves look fine. I own all the tools I’ve needed so far, so getting in there later wouldn’t be the biggest deal in the world and I could potentially make it more worth with a copper head gasket at that time. Any insight would be appreciated!
