I belive you do. You will also need an adapter plate to go from square bore to spread bore....

You should use a new manifold and adapter. I have seen adapters to a 2 barrel to a 4 but I dont think they will work in reverse. I used a stock mustang 4 barrel manifold from the 60's which is really low and everything fit on an unlifted body and stock un cut hood. Probably not the best manifold for the change HP wise but I like my stock hood. You will need a low profile air cleaner.
