Diff gear recommendations

Hey all, I'm contemplating a diff gear change from our factory 323 to 355.
I'm not looking for top of the line, but want quality and NA made, if possible. Next to zero track time(once for the bucket list)
Mfg recommendations??
Thanks
Steve
I'm happy with my Dr. Diff S-60. The highest gearing available when I bought mine was 3.54 if I remember right. I got 4.10.
4,000 rpm at 70mph sucks, but I don't do a whole lotta freeway driving.
