It's of no consequence to me one way or other, but I think giving advice on someone else's engine oiling system should be done more cautiously.
First off, I said that if it were me, I'd use them with confidence. I fully appreciate that others will disagree with me.
Aside from that, I'd be interested to know if any actual engine changes took place to warrant a change in the filter spec, or if it was done for cosmetic reasons (i.e. a bit of noise) like Ford did in the 1980 (they actually speced non-ADBV filters on vehicles where they were mounted horizontally), or if it was just to keep things consistent across their filter specifications.
I agree we don't know the whole story. However, if I still had a Chev small block, of the OP's vintage or newer or older, I'd use them.
And I did use Wix non-ADBV filters until the mid-1990s (when they began to become much harder to find) on vehicles that went into the hundreds of thousands of miles. No funny noises, no ticking or rattling, no engine seizures, nada.
