The setup will run 13's if you know how to drive and have it assembled correct.
Use the timing belt for the head you're running.
Make sure you get the alignment dowels re-drilled for the head.
The "weak sleeves" everyone speaks of is with very high RPM, or moderate boost with high RPM. Limit your RPM to about 8k, you'll be making plenty of power by then anyways.
Also putting a VTEC head on a B20 is pretty high compression to begin with, if you try to bump it up farther, you need to have the engine clayed with the cams you're going to use to determine if you need larger valve relief cuts in the pistons. Just slapping everything together and putting the hammer down is likely to net you a pretty expensive paperweight.
I beg to differ, the compression won't even yeild 10:1, it will most likely be in the 9.9:1 range depending on if its a jdm or usdm block, which isn't very high for all motor. Running in the 13's is possible though, I had a friend who ran in the high 13's with close to the same setup.
