I have a complete rotating assembly from a (non-super) eta and an is. I'll be using the 524td forged crank (same as ETA stroke) and 885 I head. What is the best rod and piston combo for hp/tq under boost at low and mid-high rpm. Will be using Megasquirt. I want to make sure whatever rod and piston combo I use clears the head without needing to machine anything.

Not looking to spring for custom piston or rods.
