Default Lm7 5.3 question

I'm building a LM7 5.3 99 and I recently picked up a 04 LM7 with newer rods and flat top Pistons. My plan is to run 15-20 psi to get me to 800hp. Would the flat tops be better for my goals or dish Pistons. I'm going to stick with the 862 heads.

Would the 04 Pistons and rods bolt to my 99 crank? And if I were to run the 99 dish Pistons would the connect to the 04 rods?

Thank you

Why not just run the 04 LM7?
