Hi Ian,
its to clear the radiator edges, have a look at GT40P 1049

Here is the front of P1049 next to my car.
There are a few cars out there with this front modification.
I am using an original Serck brass radiator and the reliefs help avoiding clashing with the thin brass envelope when the front clip is dropped on.
There are also two aluminium rubbing strips protecting the top corners of the radiator.
