I've heard this trick before and know folks that have been successful at it but I have also heard there can be risk of cutting the rope if it manages to get caught by a valve or coiled too much below the plug hole... something to think about. The shop air approach is "safer" in my opinion.

I have shop air no worries. I just need a spark plug air fitting. I have heard you can make cheap homemade ones with a air fitting old spark plug and welder.

Do I really need to have the heads tested for cracks? Is this vital? Is it a major problem with cylinder heads?
