I was driving on the parkway when a heater hose developed a hole and I lost coolant. By the time I stopped it was definitely overheated. I put everything back together and it runs OK, no funny noises or leaks, but I am wondering what hidden damage is likely to be lurking. Engine is a 350, cast iron heads. Is there anything short of a complete teardown I can do to be sure there is no real damage? Thanks
