OK, I have done a lot of research in here, read through hundreds of posts, bought too many parts, spent way to much money, and now I am ready to take it to the machine shop to have the shortblock balanced and assembled. I just want a few guys who have already done this to look over everything and let me know if I missed anything, if the clearances I have determined are good, and so on. Parts list is
B18B block, will be honed and cleaned up and I plan to have the pistons set in the hole .020
Stock LS rods with ARP hardware
Stock LS crank, PR3 pistons and hastings rings, the motor will see nitrous so I did some calculating and to me it seems at the 2nd ring should be standard gap but the first ring should be .025 inches, does that sound right?
PR3 head with GE vtec kit and headstuds (was going to use ITR's but went with PR3's for the extra compression)
OEM headgasket, stock thickness
Full Skunk2 valvetrain
Skunk2 Stg 2's with S2 cam gears
Skunk 2 IM
Profab header
RC 310cc injectors with a walbro 255 (for the nitrous coming in a couple of months).
I am having the s2 manifold machined for a direct port kit and plugged until I purchase the kit probably in April or so.
Now for the bearings, I think I may have screwed up when I purchased them. I bought all ACL standards and I am thinking that when the ARP's are put into the rods and they are resized, the ACL's may not fit and I may end up having to purchase all honda bearings so my question is, when the rods are reworked after having ARP's put in, does it make a fair size change in them?
For the piston to deck height, I have .020 taken off my head already from a previous build but there are only 80 miles on the deck and valve job so I am leaving it alone, will taking .010 off the block to set the pistons in a .020 instead of .030 still be ok on pump? I am thinking with the .020 taken off the head, it will drop the combustion chamber volume from 42.7 to somewhere in the low 41's or so? Not really sure as I have not cc'd them since doing it but that will put my static compression ratio at 12.0. Still a good pump gas compression I believe from what I have read here and being I am on the east coast and get 93.
Last but not least, we are tuning the car on crome pro but just for break in prior to getting it on the dyno, reading in the AM forum it seems I should set my cam gears to +2 I and +3 E. I know they will need to be worked with on the dyno but I am just curious if I should leave them alone during break in or bump them fwd just a bit.
Sorry for the novel but I have read everything there is to read in here for building an LSvtec and think I have it down, just want to make sure I am on the right track before taking this stuff in Monday. Thanks for any help and I hope I gave enough info for some of these questions to be answered. This is my first attempt at making power without a turbo so I want to get it right the first time
Thanks guys.

Damn, someone post a stupid question with a dream sheet of parts they don't have and a rediculous number goal, 300 people jump on the thread and tell him to search.
Someone posts a full list of specs and legit questions and can't get **** for an answer.
