You will be better off with using the std lenght sr20 rod and custom piston. Although you could go even better and raise the pin height even further and run longer then 2.0 rods. This will lower your piston speeds and allow a higher safge rev limit.

There are pros and cons either way.. id say just run the std 2.0 rod and custom pin height its easy and although ur ending up w a worse r/s ratio you won't need to rev the big motor that high anyways..

Do some reading there's a lot of good info around on the net

The ideal thing would have been to add a deck on top of your block, but that is extremely costly and complex.
As Cory said use the stock SR20 rods and change the pin height. Just keep in mind that with the longer stroke, you increase your torque and dont have to rev the engine as high
