I ordered mine balanced, and it really was good to go, nothing else needed. I do remember when I ordered the kit that the piston manufacture was undetermined (could be Icon, SRP, or Weisco if I recall correctly). I was fine with all 3, so I proceeded. My guess is it was to use as little heavy metal as possible in the balance (once rods were selected) to keep the price down. In my case, no heavy metal was required due to the light weight of the I-beams and the Icon flat top.
Bearings were good (Clevite).
Rod bolts were ARP 2000.
Total Seal file fit rings...all good parts, quality kit.
The only thing that threw me for a loop was the aesthetics of the Scat forged crank. I sat it next to my Eagle forged crank that was in the previous motor and it looked rough in comparison to the very clean lines of the Eagle forged piece....but it works great, no complaints other than it is a little "ugly", which makes no difference whatsoever.
