There's precious little room between the top of the head and the cam lobes. Not even enough for a valve adjuster nut. My guess is that's what you'll find when you remove the valve covers... a missing adjuster nut. It won't be the first time one's cracked a head. Bummer.
Heads are readily available on Ebay. If you go that route, make sure you get the rocker box with it as a matching set. They won't work if the serial numbers don't match.
As far as just getting another bike? That's a question only you can answer.
