Good exhaust gaskets?
Stockers work great with manifolds. No experience with turbo long tube headers, I did have a pretty warped long manifold made once, still never leaked. Only stock manifold gasket I have had failed was one where the back three bolts on the manifold were very loose causing the back cylinder to blow out.
If you are having issues with the bolts coming loose, buy some new GM ones with the 13mm head. The extra surface area of the washered head seems to stay tight better then the older 10mm headed exhaust bolts.
