The 460 runs good, the known issues are exhaust manifolds and fuel pumps.
When we had ours we added a Banks Power Pack system and carried an extra fuel pump. On ours there were (2) fuel pumps, on in the tank (didn't carry that one) and one on the frame rail that we did carry.
The Banks system dropped the exhaust manifold temps down to where they weren't glowing cherry red at every fuel stop. It was a nice improvement. The full Banks kit would have been better, our budget didn't allow it at the time.
