That isn't normal.
A few pictures would help. Maybe the scoop wasn't properly attached (it was a separate piece back in the day). It was supposed to be attached and then layers of fiberglass were laid over the transitions - maybe that wasn't done. Maybe something is vibrating against it.
In any case, a better understanding of the location of the cracks would help.
My immediate thoughts are that a proper repair should be much easier than fitting a new cowl and that, properly done (and with any causal factors eliminated), you should never have to repair that part of the cowl again.
