They're about the same as most chinease forged units. Are we talking 300hp 6cyl or 4cyl? Depending on the motor, a stock set of rods, with some rod bolts and maybe some shot-peening would do just fine.
However, I've seen good results in multiple platforms with eagle rods, but I have heard some things about discrepancies in dimensions, so before you put them in, I would mic all the machined surfaces to make sure they meet spec.
