FWIW - the heater shut off valves are a good idea, regardless of whether the car is run on a track. The heater hoses run through the center console to the heater core and actually radiate a significant amount of heat. This is most noticeable in the Summertime. Ask me about the time I rode back from Las Vegas in Bob Benson's Winged Beast with no heater shut-off valves. I felt like a turkey in an oven. There's also a safety aspect to the shutoff valves. I've heard of at least one Pantera that had a heater hose burst in the passenger compartment spraying the occupants legs with 200-degree coolant.
Don't try to straighten out that "kink" or bend. The copper line will split.
Good luck!
