Open up the jet in the carb. Again get the carb part number (dash number will very). Find out if you have a lean version of the carb. You can buy richer main jets for the MS 4-5 carb. It does not matter what the plugs look like. If you are running the lean version of the O360 carb.... This is a well known issue.

You have a fixed prop. How long is the prop extension. Measure the distance where the prop extension bolts to the engine crankshaft to the where prop bolts to the extension. Not sure why Dan wants this but I suspect the longer cowl has slightly better cooling. However you can as was originally suggested open up more cowl exit air area.... that will cool your engine as well.
I asked before what is your OIL TEMP? If you are running high oil temp as well check to see how many rows your cooler is. You may have insufficient cooler size. Oil keeps the CHT down.
Did you check your Mag timing? 25 degree is the spec... I would make sure it is at 25 deg or less. Again seriously 24-23 degree will help CHT.
