I run stock "706" casting heads with LS9 gaskets, Patriot duals, ARP head studs, and a PT88 in my 01 GMC c1500. On 15.5lbs it made 660 rwhp. I'm running 18lbs on the street now. If I could find better heads and gain some compression I would.

the fairmont and 88gt have 5.3s with 706 heads
the 88gt made 607rwhp through a th400 last night on 22lbs of boost.
my fairmont did 585rwhp on 18psi thru a 4l80e.
the 706s dont seem like the best head IMO but they work haha

im using the same as you OP. I hope that I can make well over 700rwhp on my setup. I plan to be stock setup heads with TU1 cam, ls2 front cover conversion and big turbo.
ls9 heads gaskets and arp studs. But will see what happens.
