ive been searching for a diagram i found a few hope i can sort it
 
yep ths had the same problem as ina manifolds aswell where we had to grind the top down...hmmmm lol:think:
 
Interesting.... especially as they even have the same mould marks on the runners....

Could these in fact be sourced from the same manufacturer then I wonder?
 
i second that 1 mate i reckon maybe bought in bulk from ina or sourced from same place as ina, as i sed earlier we had exactly the same problems as people who bought ina mani
