That engine will ping itself to death if it's really got 11:1 compression and that small of a cam. I would expect cranking compression numbers over 200 PSI with engine warm, plugs out and throttle wide open. That would verify combo of compression and small cam.
A cam with a later intake closing event, about 10-15* more duration and 112-114 LSA would reduce dynamic compression and make more power. That would be complimented by an RPM intake and Q-JET.
We could make timing recommendations, but the timing may be retarded on purpose to prevent detonation. Setting it where it should be may be a bad thing, depending on how sensitive the engine is to detonation. I suspect retarded timing why its so down on power and hot. Check what you have now and post back. We need to know timing at idle and at 3000 RPM.
The engine temps at 220 is too high. It's either water flow, air flow, radiator size or tuning. What are engine temps at cruising? What is the oil pressure at idle and at 3000?
