It's slow at work, so I'll create a diagram.

As you can see, the angle is a bit different. However, it's very marginal.

Stock R/S = 1.70

2.0 Tall rod = 1.75 (whee..)

There might be some gains due to greater piston dwell at TDC, however I would be very hesitant to expect any real noticeable gains with that small of a change. (and I am usually the "go for it" guy when it comes to weird stuff). While I have no proof for this exact build, I would suggest the price of custom pistons is not enough to offset any performance gain unless you were also doing high compression, reverse offset, gas porting or something else to warrant the custom pistons.
