I believe your overheating issue is due to multiple things, none of which have anything to do with the cam being advanced 4 degrees. Providing that was actually verified with a degree wheel.

The LSA on that camshaft should be around 113 degrees. Installing it at 109 ICL is only 4 degrees advanced and extremely common on pretty much all camshafts today, in fact most will grind that much advance into the cam right from the start.

The tune is one of the biggest factors that play a roll in how hot the engine runs, and 6 degrees of initial timing is no where near enough. I would suspect the curve isn't where it needs to be and likely the vacuum advance not working properly or in an efficient range. I would address that first before I even thought about moving that camshaft again. That's just for starters. We can address other things once that is taken care of.
