Some of the cars I have I bought after they had sat for decades. The engine blocks and radiators were long dried out and full of crusty, rusty, scale and dirt. A good cleaning was in order. Also, on one occasion I had to have the radiator rodded out. On another, I bought a NOS service replacement radiator.

On all of them I had the distributors rebuilt and timed.

I have found that a flathead will cool and work fine when all of these systems are working at 100%.

As for the low compression, I put over 1200 miles on a 21 stud with similar compression readings last summer before I pulled the engine and installed a rebuilt engine. It used a lot of oil but I was having fun.
