If its the later style steel tubing under the pushrod cover, I have never seen a replacement. I have used standard brake line when I needed a new line. You may have to change the longer fitting that typically comes with the generic fitings as the longer fitting generally does not clear the bump out on the side cover. Notwithstanding, clean the original with pipe cleaners and mineral spirits. Little elbow grease adn it will be all clear and clean ready for another bunch of miles. Remember to clean out the fittings and passages. Becareful, some of those fittings are specific to the year of the motor. For example, if you look at the brass fitting are the rear cam bearing boss on a 57 motor, you will note it has a restrictor built into the fitting. Later motors do not have this type fitting. So keep track and clean clean clean and off you go!
