Two tone...should I ?

IMO ford, chevy style, flattish black engine compartments look really tacky. And gloss black would be too dark to work around, and show dirt and be very hard to keep clean looking.
Hood scoops, matte black hood looks fine to me, but it's your car.
FYI, the AAR/TA hood/top of fenders were matte black, but they taped off the top of the fender mounting flange so you had both the matte black front end with the hood closed, and the body colored engine compartment with the hood open. Kind of a best of both worlds.
