the std here is typically dry on the heads and manifold, a smear of cement (if anything) to bond the gasket only - but silicon accross the deck top between the heads.
You may need to check the angle of the manifold face vs the angle of the heads.
The injector bosses, in some cases, are welded onto the manifold, in this case we remachine the manifold face where it meets the heads as this area will distort slightly.
I hope this helps, Regards Paul
