Manifold gaskets

[lowfat_hg]

Guys, just i the process of fabbing up some exhaust manifolds and turbo system. The original manifolds dont use gaskets so will i need some with the new custom items?
I think i will, so where is the best place to get them?
cheers

The engine I have, has multy layer s/steel gaskets..
High temp copper silicone can be used and works well without any gasket... My turbo headers have the primery slightly proud of flange, to assist sealing...On my Ford we have used tefflon O ring's. Cut from high pressure hydraulic hose...
