What manifold gasket with turbo manifold (5vz)

I've been using CX manifolds for 2+ years and I used the gasket they supplied. It's a thicker type gasket. Last time I went to the track I came home with an exhaust manifold leak. What does everybody use? Stock gaskets or something better?

 

I guess I should have posted this in the Turbo BS thread?

 

I picked up some copper gaskets online a few months back. I haven't used them yet, so can't say anything about quality or problems. They look nice tho and copper gaskets are supposed to be great.

Thank you. I thought thicker gasket would take out some of the warpage if any develops, but I keep seeing these copper gaskets being used.

 

Copper gaskets are softer than steel gaskets and can form a better seal. You should have your manifolds resurfaced before you put them back on, then torque them evenly the same way a cylinder head is torqued. This should keep everything flat and true for along time.

 

I'm using the OEM MLS gaskets with good luck so far.

 

I have a set of OEMs off a used motor I'll probably just throw those on. I wish I hadn't used that gasket that came with the kit... I knew better.
