Spark Plug question

[RoliO]

I've searched but did not find the answer. Anyhow, what is the gap spec on the plugs for the 5.3L (2008 model if it matters). I just got a set of OEM plugs and want to swap them in this weekend. I think the gap is 0.040 but just want to confirm. Thx!

Well after many online searches I found some info on this. It seems that GM changed the plug gap in 2004 to 0.40 so that is what I'm going with.
