1991 Silverado-L33 5.3L, 212/218 .557 .562 115+4, ASP under drive pulley,180* thermostat, 90mm truck intake w/ LS3 throttle body. Shoenfeld conversion headers and duel Flowmaster exhaust. Performabuilt LVL 1 transmission and 23-2500 stall converter.
now what 6.0 heads you thinking? L92 or the 243 since you have a gen IV?
317s on a 5.3 net you 8.4 cr extremely low,
your better off with 9.0-9.5 for most builds
2002 Lightning - GT headed 5.5Litre w/ Twin 7665s
2002 Silverado - 427Lsx w/ Twin gt4202s
2010 Silverado crewcab Z71 - 5.3litre w/ procharger
2000 Wrangler - 5.3litre with some stance
2014 Xsport- 3.5 Eco boost

it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference
The 317's are the only ones I have looked at so far. I would be interested to know what you would suggest though.
