Chevy "high-cheek" rods?

That particular rod you mentioned was found on 66-67 327's. They were small journal, and had added mass around the area of the rod bolt head boss.Early 283-327 rods used to break where the rod bolt heads and the I beam portion of the rod came together. The later rod flares out at the point where the I beam meets the big end and they used to stay together better than the early (62-65) vintage 327 rods. They would work better on a 283 , since all those had the earlier rods. I went through all my engine parts a few years ago and let all the weaker rods go. I wouldn't use an OEM rod in a stocker motor again anyway. By the time you get eight cores, resize, mag, shotpeen , new ARP or SPS bolts, etc. you might as well buy a set of Manleys. But, whatever you do, check the big end for size and roundness. Just because its new, doesn't mean its right.
