Default LS3 heads w/ hollow stem valves and .650 lift springs for sale

I have a set of brand new LS3 heads with brand new GM hollow stem valves and a set of patriot performance gold .650 springs for sale. Everything is new and disassembled. In the process of them sitting in the garage I lost a couple valve seals but everything else is there. 823 casting.

$700 shipped

Correct. 6.0l or bigger (4" bore).

I want em, but I just can't dish that much out with the 5.3 project on my plate. Too bad too, I could toss these on the GTO and use the 243s on the 5.3! lol
