An improved internal combustion engine of the desmodromic type having a novel connection between the valve stem and the rocker arm assembly. The connection includes a shell which captures a pin which has an enlarged opening which surrounds the valve stem. As the valve end of the rocker arm assembly moves through an arcuate motion, the pin within the shell slides within the shell which, in turn, is tightly affixed to a valve stem. The valve is forced to close either by a spring or a second cam.
