I’m confused, I have the oem torque specs but k1 rods came with another torque specs for like 5 different rod bolt sizes. Anyone know the true torque spec for k1 rods in a 6 bolt? Thanks in advance

You won't use the OEM torque spec, you will use whatever is specified by the rod. What size bolts? What type? If it's the typical ARP2000 3/8-24 I'd suggest it's somewhere around 40-45ft*lbs with ARP lube, but I've never used K1 stuff so IDK. It's important to use whatever torque they specify, because that effects the roundness of the big end bores. They torque it to a spec, wether ft*lbs or a bolt stretch number, and then hone them round. Provided you match this torque/stretch the big end will be round again.
