leaking manifold after update install

[Shield13]

I just had head studs egr delete new oil cooler coolant filter etc done, now there is a small leak near the back off head on pass.side, when i start it up there is a tiny amount of boubling at one of the exhaust manifolds. It soon goes away when it gets warm. The manifolds have not been touched.

I'm a little confused, do you have a exhaust leak? I've never seen an exhaust leak bubble, or is it a coolant leak? If head gaskets were done they usually pull the exhaust manifolds off so they can resurface the head.
