ok- the 67 327 didn't come out with 202's from the factory on the 327-300. You can look on the top of the heads below the valve covers and find the numbers. If they are double humps the numbers should read 3782461, and they are 194's w/ 151's.
You won't need 202's on it unless your going to run a blower, or another means of forced induction, it will not pull anymore than the 194's can handle - so's it would be a waste.
Good- luck
