I've been reading here regarding heads and cracks. It appears that they are very common. I have mine at the machine shop now (1951 Chevy 216 ci) and have been told I have a few cracks in the combustion chamber. As I was taking the engine apart I did not see any water/antifreeze in the oil. The creacks were determined during magnfluxing. Has anyone just left them and the engine runs fine? What is the recommendation? I've checked into sending it out and having it repaired and that is costly (and undetermined until thay have it).
I'm asking as it is my understanding that on some auto's it is common to have cracks and they are just left and all runs just fine.
Thanks Kevin
