SU carb needles

![Default](/forum/images/icons/icon1.gif)
I have the original dual HD8's and hisser (ASC) that came with the previous 1970 2.8 litre engine in my XJ6. The new engine is a 4.2 litre from '73 and comes with HS8 carbs and the probably wonky AED. I would really like to try the already cleaned up HD8's on the engine when I install it, but the needles in those are UVX and not UM as I am supposed to use with a 4.2 engine. It would work anyway, right? When I look at the needle curves at http://www.mintylamb.co.uk/suneedle/, they look fairly close, or am I missing something?
