How hard is it to change glow plugs on a 6.4?

Hey guys. My truck threw Code P0674 so I guess I have to change #4 glow plug. How hard is it to change the glow plugs on these trucks? Also, how do I know which cylinder is #4 cylinder?

Oh man thanks so much for the info. I couldn't find any info on the 6.4s. I thought I would have to pull off the valve covers. One local garage told me I would have to pull the cab but I thought he was on glue. Thanks again!!!

Yea, if you need instructions on something else I probably have something to help. I wish I could find some articles like these on the duramax too.
