L.I.M. nightmare,need help

Im working on a 3400 (Aztek) , did head gaskets, machined heads (overheated), did L.I.M. gasket, however still had leak at L.I.M., removed and did again, still leakig after using new torque specs and T.S.B. info...never did check manifold for warps, Im ready to dissassemble again, has any one seen these manifolds warp? any thing I may be missing here??
Thanks

Welcome to AF. How much were the heads resurfaced, this can affect the manifold fit, wasn't mentioned by your machinist? Check the manifold surfaces with a machinists straight edge for any warpage. How do you know the coolant is being lost thru the intake? Lots of questions, right?

Thanks for the reply, I was told the front head was out .007 the rear was ok, the leak I can spot with my flaslight, maybe I have warpage or a crack I never saw, Im realy curious if anyone has had this reacurrence.
