What do you think of my odd combo?

What do you think of my odd combo?
LQ4 6.0L, stock pistons
PRC Stage 2.5 5.3L heads 60cc chambers
.045 Gasket
Howards 226/232, .578/.587 cam, 115 LSA
SLP 1.85 rockers (.629/.638 lift on cam)
Stock LQ4 truck intake, TB and MAF (wish I had the money to change this!)
Pacesetter headers
3" x-pipe, Jones maxflow mufflers, turned out infront of rear tires
This is through a 3,000rpm stalled 4L80e, 4.30 gear 8.5" 10-bolt
Car hasn't seen the dyno yet but has been street tuned using a wideband and HP tuners and seems to pull really hard.
Any input on my timing curve? My research has given me a lot of widely varying information. Right now it's 24 degrees from 2,000 to 4,400...drops to 22 degrees at 4,400, then ramps up to 26 degrees by 6,000 to 7,000rpm.
