Unless you are using a flat tappet cam, I don't see any reason to do the extended 2000 rpm run for intial break-in. That is usually when you can ruin your headers. I have heard of several people hurting their coated headers when they are breaking in a cam. If you are using a flat tappet cam or are planning to run the engine like that on break-in, I would use other headers for sure.
