What are the advantages of H-Beam rods over stock rods in a 2.0L motor? I know the H-Beams are lighter and stronger but in terms of performance what are the advantages of using the lighter rods?

I'm going with an upright fan conversion from Fat Performance so that is the belt pulley. The clutch and flywheel weight 14 pounds together, I think the flywheel is around 8 or 9 pounds. It's from Patrick Motorsports. I'm not convinced that the Fat kit was the best money spent when there are other options out there that would probably work better. I bought it years ago and decided to give it a try. Chris at Tangerine has a flat fan setup that I wouldn't mind giving a try, maybe next year when I recover from how much I've already got in this build. Jake also has his DTM setup that directs the airflow to each cylinder and head that may be the best option out there but I'm not a big fan of the aesthetics of it. My goal for this engine is a very light rotating assembly as there is a bunch of accelerating and decelerating in autocross. This will change the whole nature of the car. Here's a pic of the clutch and flywheel setup.
