6.0 rods help

Hi, new to the forums. Building an iron block 6.0 for my swap into a newedge. Using stock crank, flat top forged pistons with valve reliefs, ls3 heads and intake. Plan to procharge the car but trying to figure out what rods I need. If i use stock length or 6.125 rods my fear is it will be too much compression. Is there any way I can do a shorter rod to lower compression a couple points?

I already have the machine work done. Had to bore the block .02 over due to damage and have the pistons already. Would like to use what I have. Thank you in advanced

You’ll have to use a rod length that correlates with your current forged pistons….different rod lengths require different pin heights. I’d use what the shop set you up with.
