[Healeys] Over heating and adding additional core tubes to theexisting radiator

[Michael Oritt]

Robert--

I'm sure you'll hear you should definitely NOT wrap the exhaust system with
lagging as it will cause its early demise due to rust.
I was told that 18 years ago and didn't listen--my steel headers are still
intact.
