If and when you sell, how the buyer or prospective buyers regard this depends if they are puriest or hotrod -der types, hopefully in between. You can always do this, pick a spare hood, and have one with the scoops added. That is your best solution, and IF yo paint the car, paint both hoods.
Me, I tend to keep more valuable cars stock or easily changed back to stock, and less $$ type cars I tend to change, to suit my tastes. An original 70 340 Duster is a pretty decent $ car restored. But the change yoy are talking is easily solved with a spare hood right. Yes a good body guy can, weld and fill or fix anything for a $.
