I'm 6'1" with normal (?) proportions and generally ride 59 - 62cm frames. Preference is for 58cm top tubes with 12cm stem. I have a bike that is 56.75cm tope tube with a 13cm stem that works.
On your frame the head tube is 19.0cm? That's plenty tall for a big guy. You need more saddle set-back and the 14cm stem. With 'normal' flexibility you should be OK. Maybe.
edit: maybe not so flexible now that I see the stem raised. How about bars with more reach? AND the setback seatpost.
