Heli Head for cowled engine?

I recently bent a con rod for my os 46 fx. I am getting the replacement, and I noticed that a heli head is only $30. This engline is cowled with about 3/4 inch of head above the cowl, and is running a MCM, with 11-7 prop, so the load is quite high. Should I use a heli head for this to keep temps down?

Only if you need the extra weight in the nose otherwise keep it rich and make sure there is air going into the cowl and coming out.
