LX9 exhaust manifold gaskets - best brand?

[Starglow]

I'm doing the 3500 LX9 swap on my '99 Grand Am and want to use LX9 exhaust manifolds from a 2006 Chevy Uplander instead of the smaller port 3400 manifolds. Rock Auto offers three different vendors (Fel-Pro, DNJ Engine, & Victor Reinz) for the LX9 exhaust manifold gaskets. Which of those three is the best choice or is there another preferred brand available?

I also need suggestions on the best exhaust manifold bolts/studs and 3500 UIM gasket choices.

Thanks.....!
