So i had a machine shop do some work on the head and i asked about the hair line cracks on all the cylinders he said its fine its just surface cracks and there was no leaks as he did pressure test on the head.
So i took the head to a second machine shop to do some other work and they have told me the head is bad due to the cracks.
can anyone tell me if these cracks are bad to where i need to replace my head.
