I run 'em if I can, but questionable if they're necessary and some builds just don't allow for it, for reasons stated above and more.
But there are differences- I've got a whole stack of these on the shelf, and it seems every time I look for a pair to use they're a bit different, be it for a 904 or 727, and the above mentioned 318/360 difference (which is a new one on me, never heard/considered that before), and yes, I have some that came off manual trans too- 360 truck, but not sure about 833s; my memory is failing me on that one- it's been a lotta years since I've seen an unmolested one. And probably variations in each depending on year and whether they had a right angle filter adapter or a cutout for the straight filter, yadda yadda yadda.
Long story short, run 'em if you want to, no big deal if you don't.
