From my expereince with the LS engine, I'd throw rods/pistons(forged) at the bottom end, give the head a nice port job and call it a day. Use boost for the rest of the power. With mid sized t3/t4 to provide the positive pressure, you'd be sitting pretty. A good forged rebuild will give you the reliablity you're looking for, just don't scrimp on the tuning aspect. Stock LS engine's are notoriously reliable under boost, even under large amounts. I'd go with something in the 9:1(stock) compression range to maintain the "peppiness" of the engine out of boost. Plus thats a good static ratio to make good power under boost without having to provide lots of it.

As far as your parts list, doesn't look like you've got much of a budget to me. If you're gonna go with a COMPLETE head rebuild you'll be dropping some $$,most of it unwarrented. Lemme nit pick a bit, i'd ditch the cam gears/ss valves/guides/ect. If you're not going to go full all out race, its not neccesary. Unless you're going to rev over ther stock red-line(no point without cams), the valve springs won't be doing much for you. I've got the 500whp mark right in my sights on my engine, and aside from a little port work/crower top-end(cams/springs) my head is stock Honda parts. A nice port match and maybe a 3/5 angle valve job on the stock stuff is just fine. The LS head isn't as bad as everyone makes it out to be, it's biggest downfall IMO are the cams. Just food for thought and some ease on your wallet.

The SRP/Crower combo is ok, I'd go with Eagle rods just becase they are nearly 1/2 the price for the same performance and they come with ARP rod bolts. If the SRP's are your thing make sure you get thier "Turbo" pistons as opposed to the "N/A forged" pistons. Those are "supposedly" not much better than stock honda cast pistons. The head studs are an excellent purchase, no gripes there.
