to make big hp on a 20V if i remember it right you need the right bigport head, and if i remember it right then the 3. valve dont make it flow more.
VAG 20v engines in good health do not consume anywhere near 1L per 1000km.... THat's 1L per 600 mile
A std port 20V will make 350hp easily, the big port head you mention is readily available as it was fitted to the early 150hp models.
