Exhaust Manifold to Head Question

[Gavin]

Hi All,
Are these 11121744057 studs used to work with the N54 engine for installing single turbo manifold.as for the copper nuts would these be the short nuts to use 11721437202 with these studs?

I'm pretty sure that is right. It depends on the manifold of course, but those look right to me at first glance.
