8,9,psi Without Meth?
'01z LS6 with a 3.85 pulley so I'm guessing I'll be somewhere between 8-10 psi with headers and mild ported heads, stock cam.
I've just spent a boat load of cash for the stuff to put my engine back together and also a Procharger kit that has a few loose ends.
Well, I'm about to buy those loose ends and I'm confronted with this issue.
I spent money that I was going to spend on an ECS Alky kit (the last piece of the puzzle) on a set of longtube headers/cats/x-pipe.
I'll have a Lingenfelter fuel pump to help with fuel, can I just cut the timing back to like 14 degrees and look for knock until I can pony up for the alky kit?
Or should I just get a 4.15 pulley right now as a trade?
Advice please. THANKS!

But if you are going to be hitting boost alot. I would upgrade the springs in the heads on it and harden push rods also. I sure the stock ones will work for some time, but if me would hate for it to happen to you...

That's what I was thinking.... glad to hear someone else say the same.
The whole engine is apart.... and it's 100% polished... even the block! 
So the heads have new '02-04 LS6 springs, seals, etc. (the whole engine has new gaskets since the timing cover, valley cover, everythig else is polished. It even has a polished Weiand intake. Coils will be relocated and the wiring hidden/minimized.
Couple quick iphone pics of various batches.
Mock up before I did the ac compressor, ebcm/bracket, cradle
The top end
Alternator and bracket
The powersteering pump is done and has a polished billit pulley, the steering rack, polished headers, engine mounts, etc... EVERYTHING

Not paying for a dyno tune. Dropping in a base tune from hptuners website, cutting a bit more timing, adding fuel, and then street tuning it. No cost.

^ Thanks! 
There were some delays in life since I started July, '09.
Got married, became a father, bought a house, etc so it's been a long term project. Finally coming together before my birthday at the end of November.
I didn't expect to have a polished blower hangin' off the passenger cylinder head so the final result should be sweeter than I had planned.
The last twin turbo LS1 I had was done in 3 months slaving away after work and on weekends in my garage. Pictures of the last engine are in my sig. It was fully polished too.

The guy mentioning the springs is dead on. Eventually you'll want some dual springs to keep valve float under control etc.
What you should be worried about is keeping it shiny side up.

You should be fine without the meth as long as the tune is good. Keep in mind that you will want to tune the car again after you add the meth kit. It would be cheaper to add the meth kit now unless you do your own tuning. Just a thought.
Nice work on the polishing.
