Abstract

An apparatus and method of attaching an exhaust manifold to an engine's cylinder head utilizing an oversized hole in the manifold, a stud fastener extending through the oversized hole, a spacer element around the stud fastener, and a nut adapted to be tightened to engage the spacer element and the flange wherein a flat gasket is compressed to a desired extent which is not so excessive that it inhibits sliding movement caused by thermal growth of the manifold.
