I decided to buy the AeroVee “Fence” baffles even though my engine is not an AeroVee.
My engine has the Hummel 94x86 Nickasil plated aluminium cylinders so the engine is a touch wider than the AeroVee and the Cylinders are shaped differently.
All this meant modifications would be required and in the end I remade the back fence baffle and the two front corner baffles. The other parts fitted as designed.
It was great still having the AeroVee kit, even for the parts I had to re-make the AeroVee parts gave me a good starting point, it would be a pain to have to design this from scratch.
You can see some pictures of the semi-finished product here:
