Almost exactly like my build but i am going with AI 190s and a BRE cam. I would really recommend dyno tuning if possible. The shop I am going to runs about $75 an hour but well worth it.

I am going with the mahle power pack pistons -5cc flattop almost as light as JE and I am using scat 6" Forged I beam rods with 7/16 rod bolts. The reason I am going with the I beam is because of weight and they say they support up to 750 crank HP. I have no need for H-beam because I am not using any type of FI going all NA. also stock crank turn and polsihed the whole assembly balanced, and studing the mains. I might end up splaying it 2 a 4-bolt if its not an outrageous price.
