The engine wouldn't stay running because the rockers were too tight. Might assume it's a new cam. I'd be more worried about a bent valve.
I'd run it and be sure the cam breaks in ok, I guess it's a new engine, break the whole thing in to get the rings seated too. Then take a compression test, paying close attention to the cylinder that bent the pushrod.
If the valve head is bent a little it might run ok, but it'll eventually break the head off because everytime it closes it flexes it back close to straight. That slight bending back and fourth will lead to valve failure, which will lead to piston, cylinder head, connecting rod, and possibly block and crank damage because valve heads don't compress. Valve head broke.
