That seems about what the 5.3 on my truck idles to.

I don't have a 5.2, but on my 6.2 with 155,000 miles, my hot idle is in the area of 20 - 25 psi.
My '04 L59 with 114K on the clock runs about the same at hot idle. I recently had the oil pan gasket replaced and had them change the o-ring. Didn't make any difference in the pressure, but you know, while they were in there... the old o-ring came out somewhat hard so I'm glad I had them do it.
