[Purdy Swoft]

Because the broken stud must be removed without causing damage to the cast iron threads in the block

. The valve guide is held in place by the valve spring .

With the valve spring removed , the guide is easier for me to remove than a broken stud .

.Sometimes the head has to be removed , no matter what .

I just try to avoid removing the head unless it is absolutely necessary .

I'm not trying to be a smartazz .

I have seen that Railcaarmover knows his stuff .

This is just my preferred method and why .
