1uz exhaust manifold bolt patterns

[stradlater]

Is there any difference between the exhaust manifold bolt patterns on different versions of a 1uz?

I'm thinking of buying some later model cast manifolds to build turbo manifolds off and am wondering if the bolt patterns are the same.

no difference

edit: although the port dia and corresponding gasket does change somewhere. that may be 2uz, but im not sure
