Something struck me as fishy as soon as you said it was repairable but you were getting another engine anyway.
Generally I would assume that Suzuki wouldn't pay for a brand new engine if the old one was repairable. Then it turned out you weren't given a new engine. Sounds a lot like you lost a new (repairable) engine for a used one with a bad valve cover. I would've just brought it to the next authorised Suzuki dealer. Especially after raring they were closing soon. Why agree to let this happen?
To add insult to injury these guys scratch up your bike and keep you in and out of the shop. Sounds like a real pain in the ass experience. Guessing this is your first bike?
