Definitely use a baffle with larger volume. I have tried 3 different types over the years.
The small Jabiru baffle with external plug leads. I dont think they had enough volume.
The Sonex metal ones they worked but tended to crack between the cylinders.
I then modified the old jabiru fibreglass ones to a similar dimension as the sonex metal ones. I did cut a small slot in the upper part of the baffles internal deflectors to allow more air through to the rear cylinders. I think that alone made the biggest improvement to equalling the temperatures

Or for that matter, should I consider the LCH head option?
I wouldn't bother. The engine can be set up to cool properly without the added weight and complexity. There is also barely enough room in the engine bay as it is.
