Contact Bill Rogers at Valley Power Products 800-609-5110, he will help you out of what ever problem you may have. /forums/images/graemlins/grin.gif But be forwarned, these parts are not cheap, last I checked head gasket was $125 piston rings $90 per piston /forums/images/graemlins/confused.gif, but you will not find them any cheaper anywhere else and the service Bill gives you is worth giving him the business!!! Good Luck
