A valve guide is received in the aperture and a valve stem is received in the valve guide. A valve seal support includes a radially outwardly extending flange disposed against a surface of the cylinder head external to the recessed pocket and a cylindrical body that extends into the recessed pocket. A valve spring contacts the flange and a resilient seal is secured to the rigid valve seal support and in sealing engagement with the valve stem.
