3100 to 3400 head swap, exhaust manifolds compatible?

[dnalbach]

I'm in the process of doing the 3400 head swap on my 3100 engine and I haven't noticed offhand anywhere if anyone has said whether the 3100 exhaust manifolds will still fit the 3400 heads. They bolt on ok? Do you use the 3100 exhaust manifold gaskets or the 3400?

Same manifolds and bolt pattern so no problems there. Either gaskets, its all the same.

Thanks Ben.
