Thanks for the update, everyone.
If I do buy a new pair, what would you recommend? .92 or even larger? I know 1.03 are available but those seem awfully stiff

Mostly street, occasional strip. Forget the 90/10 shocks, I think those would be really weird to drive on the street.

I'm not planning to go autocrossing, and soon will be installing homemade (2x3 box tubing) welded frame connectors. The big-block A-body is already nose heavy and I eliminated the back seat which probably makes the weight distribution slightly worse.
