SU HS8 Carbs Damper part number!

I have some HS8 carbs , the needles are BCC , the dampers have AUC 8110 and AUC 8111 on the black plastic tops , the difference is the brass bit at the bottom is a little taller then the other ,
Carbs are going on a 3.4 XJ6 Engine , what would be the best dampers to use ?

I have a book by GR Wade on SU’s. In the back are factory specs.

For the HS8 3.4 XJ6 it lists:

needle CUC1169
damper AUC8102

Cheers,

Rob

Thanks for that Rob ,
