Cuda cowl painted body color or black with Shaker hood

I have a 1971 Cuda B5 with a shaker hood. Is the top of the cowl by the venting supposed to be body color or painted flat black? Mine has been stripped and primed so I have no evidence of what it had.
I had an original B7 Cuda with a rallye hood in the 70's and it was body color. I have seen a few shaker cars lately with the black out and wondered if shaker hood requires this to be black. Any information would be appreciated. Thanks
