 I have a leak on the #4 port of my original 32 year old exhaust header on my '74 JH. Not uncommon , as I understand. My questions are: Is the engine in any sort of jeopardy of damage, such as a burned valve, if I drive the car until I replace it, and what is the degree of difficulty in replacing it with the newer ones that are available ? Any and all help would be apreciated. Thank you....
