Yes the heads swap as a complete assembly. The later engines got a whole list of updates not just the head.
If your on a tight budget - get an early engine and a spare head and port it. Good for at least 20HP so 295HP is not a bad number. Add a good header & tune and I bet you would be close to 305.
