Unless they are trashed, which you’d be able to see, they are likely not a problem. Those are positive locking type seals. And if they’re torn during assembly they will leak oil past but they’re pretty durable. If they are all down on the guide boss and not visibly torn I’d not mess with em.
Think I should venture into taking a spring off to look or just leave it as is and move onto new plugs / fuel / timing . . .I can just see the red rubber part through spring but can't make out much else
