It's only .010 longer.Instead of 6.625 is 6.635 The standard Chev bearing is the same size as a .050 under Pontiac journal. Easy to get bearings, that's the big advantage. The BBC rod is 50 grams heavier as well.
No great injustice here so relax.

Todd, pretty sure he meant it is 0.500" longer than the stock big block Chevy rod, which is 6.135" long.

The FE Ford was also allowed to use an aftermarket big block Chevy connecting rod before the aftermarket made rods specifically for them.



On the original subject, these days most of us try to get our piston company representative together with our ring company representative, and make sure the ring grooves and rings are well matched. I've found that my friends at JE and CP have no problems talking to Keith at Total Seal, and making my pistons match my rings really well. I do not do much to my rings or ring grooves when I get my parts.
