Exhaust Manifold Gaskets Or Not?

Hey everyone, so I'm at the point of my engine swap where I cleaned up the stock manifolds and am ready to install them. I have some exhaust gaskets that came. With the engine rebuild kit. I read that stock, though, was metal to metal.

Should I use gaskets or not? I read a lot people mention either direction. And a lot of people that said they had leaks with gaskets. I'm fine either way, but would love the advice!

 

More leaks without gaskets. And if you do develop a leak the gasket typically takes the abuse. No gasket the the cylinder head or manifold takes the abuse.
