I woundn't get too bogged down with whether it's a road ace or a competition. I've got both and neither looks like your frame. My Road Ace is the 1st gen one with over bottom bracket cable guides, while my Competition came as a Team Coloured frameset and does not have the shot in stays.
The moral is (if there is one) that Raleigh built many frames over the years and I would hazzard a guess that they built lots to the same design and just sprayed them up to what ever finish they needed.
I may be wrong on that point, but since you are not intending on replicating a road ace or competition, I see it not mattering. If it's in your size and you wanted a Raleigh then great news, built it up and paint it as you see fit.
