An exhaust manifold joint includes a number of like exhaust manifold segments mounted to a corresponding number of cylinder heads of a large diesel engine. The exhaust manifold segments slip relative one another to accommodate thermal growth differentials between the exhaust manifold segments and the cylinder head. The exhaust manifold segments are further mounted to the cylinder head via fasteners that extend through a bolt hole of the exhaust. manifold. The bolt hole incorporates a reverse counterbore at the manifold to cylinder head attachment to move loading of the fastener away from the attachment, thereby resulting in elastic deformation rather than yielding of the fastener during loading of the fastener.
