Delta does not have International First Class but BusinessElite.
Either way, the answer is no. The A330s and 747-400s all have the NW
angled lie-flat seats still; the 757-200s are all cradle seats that have about 150-160 degrees of recline.
A lot of the 767 fleet (all -300s still, though I think the -400s are pretty much done) are also cradles.
