I need a few suggestions on an engine build-up
Ahh yes. Springtime rolls around and my truck sits in storage, two rods piercing the block. A familiar story to most, I knew it was going to happen - I was saving money since last year when I observed smoke on start-up. For this exercise, we are going to assume that my LB is a total loss. I'm fairly confident that the crank is galled and the heads took significant damage while earning honor in death. 
My current inventory of significant power-adder mods are: MP blower, 4# and 6# lower pulleys, C/L intake, SBTB, BA2800 MAF, Predator programmer, and a Tru-Flo filter. I'm going to hold on to the MP as I believe in it's potential - JDM can attest to it's abilities, in the proper configuration.
As it stands, I have about $8,500 to spend. (now) Some of this coin is going to have to go toward fuel system upgrades, (injectors, pumps and possibly lines), coilpacks, e-fan, headers, Canton oil pan/windage tray (my oil pan is swiss cheese) midpipes and a good A/F gauge. I want to "right size" my motor
for my purposes, and get the most suitable engine for my dollars. I do realize that I'm going to have to spend more money to get some of the supporting components listed, again I want to be sure I get good pricing on an engine.
My power/usability goals is to build a "response" machine. Drag racing is only about a once or twice a year endeavor. I want "streetable" power, quick roll-ons and a good spread of power across the band.
Let me run this by you guys and get some opinions: so far,my research has prompted me to want a SB that is built with 9:1 CR. Stage II heads, like Patriot, with Stage II cams, and springs with a fairly high seating pressure. Shorty headers vs. Long headers, which favor power (torque) in the lower end and midrange (response again). I would like to ideally see about 600HP when I'm done.
So given these variables, what do you think? My post really has a dual purpose: 1. Get suggestions on the best component combinations for my purposes and 2. Get suggestions on vendors for said products. Vendors: if you have a package deal that you can put together, please!

I would get a block from JLP if I were in your shoes. He has some awesome blocks and I am pretty sure some of them are 9:1. Give LFP a call when the time comes to get the pumps, injectors, and coil packs. They have the best prices out there on those. You would probably want the Walbro Twin 255lph pumps, Siemen Deka 60# injectors, and the (Improved) GMS Coil Packs. The stock fuel line a just fine for 600 RWHP. Stage II Patriot heads kick-@ss. I have a set and they rock. If you go with Patriot, you won't have to get springs. Their Stage II heads come with Manley springs that are good up to 0.600 lift. You should probably go with some Comp Stage II Cams. I went with Crowers but I am kind of regretting it now. They have higher than normal lift (0.581) and I am scared the valve springs are going to wear out after a while. The Comps have lower lift (0.550) and more duration which is what you want for power. You can get them from RPM Outlet for $550, but you may find them cheaper elsewhere. My honest opinion about shortie headers is that you will regret it. I would just go ahead and get the LT's. I have JDM/KOOK LT's and my response is great. I would get the E-Fan from JDM. It is a little pricey, but in my opinion, it is the best E-Fan Kit on the market. With that combo you should be able to reach 600 RWHP. That MP Blower is going to hold you back a little though, but you should get there.
Good luck and let us know what you end up getting....

Sounds to me like you've already made up your mind as to what you want? Just need to decide which vendors to use.
Reading your post I kept thinking what you want is low rpm torque.
1) I'd stick with a stock convertor to keep that "punch".
2) A nearly stock motor with *mild* porting and stage 2 cams. (stronger rods and pistons)
3) A 6lb lower pulley.
4) Port the stock manifolds and keep all 4 cats
5) Set your goal to 500rwhp and BIG low end torque.
6) 4.10 gears & a True Trac diff
7) A single blade TB

My pre-cats are damaged from the engine failure. The reasoning behind keeping the pre-cats is backpressure, hence low-end torque.
