When you ask ,"Is it worth the effort", Compared to changing the head, I would say YES.
You need to make sure to follow the instructions to the letter.
If you have a source of compressed air available ,great. If not consider something like a turkey baster to blow out grit particles so they don't get into the cylinder.
You could use a type of vacuum to keep most of the garbage out, just be careful that no gasoline vapor is in the area.

My experience (on a Lincoln Town Car 4.6L which is basically the same engine):
I had a spark plug blow out and had it repaired by a reputable shop (likely not with a Dorman part) and it worked great for about a year. Then that cylinder lost compression. I believe a metal chip floated around in the cylinder until it got in the wrong place and scored the cylinder.
I don't know of a foolproof way to ensure no chips get into the cylinder no matter how careful one is.
