There really aren't any major "cooling issues" with one engine manufacturer over another. Some might be more sensitive to poor air flow than others, BUT all engines benefit from proper cooling/airflow.
The biggest benefit (besides a repair bill) is the increase in power over a hot running engine. I continually read about people complaining about how they need more power, which engine has the most, which is the best, etc..... On a hot summer day when density altitude and everything else is against you, I can guarantee you will notice the difference with a well baffled engine. I have done some testing with baffling vs non baffling and temps, there is a definite difference noticed.

On the 105, if I am not mistaken, they used industrial cylinders/pistons. They will probably be least affected (less critical need) by poor airflow. Larger clearances, more fin area.
