I did make sure that the pins were in place when I tensioned the belt and then turned it over by hand and made sure they lined up again.
I just read up on how to do it the right way and it all makes sense now;
Pin the 3 pulleys.
Slacken the two vernier pulleys and rotate them fully clockwise.
Fit the belt.
Take up the slack with the tensioner (the cam pulleys will move accordingly as the belt tightens) and lock the tensioner in position.
Tighten the cam pulley bolts.
Remove locking pins.
Doing it this way ensures that the timing is spot on because the camshafts are permanently fixed in place. Any movement in the belt when taking up the slack is lost in the rotation of the cam pulleys without interfering with the actual camshafts.
I think I will retime it again using the above method as its possible that my timing could be out by a degree or two.
