I would sell em and put the money towards a good turbo.
Or somewhere else that would bring a better bang for the buck.
From what I have read (and I am sure someone will correct me if I am wrong) until you are approaching that 800+ HP range, you are not going to have significant gains with better heads, especially on a smaller engine like a 4.8.
If you have them just sitting there an no hopes of selling them or no other use for them, then sure, put them on and crank up the boost.

i got stock 862s on mine, 835wheel, and i am approching the max on em. although it still gains good power with increased boost. it made 618 on 20# and 835 on 25#, but thats still a low number for 25psi.
to answer ur question, yes they will perform better, prolly way better infact. but u can get the same numbers from the 862s. u could make 650 wheel with the 862s on 17psi or make 650 with the good heads at 15psi.
truth is, u will never notice a difference.

And op, I got the ls9 gaskets here, only way to go! Arp studs over torqued to 95#s
Idk how hard u are gonna push this thing but if your are gonna see 18+ psi, pm me for a nice custom touch on the ls9 gaskets
