I wanted to post because I am always bragging about this and I finally had an oppertunity to time it. I removed the headers I just made to have them coated.

10 minutes to raise the car and put it on jack stands.
33 more minutes to completely remove the headers.

They do not require ANY other components to be removed or touched. So, I could start the car and drive it away, to headers laying on ground : 43 minutes.
