Wider foot-- like broader tappet face? These are mushroom-style tappets, right?

What do you need to swap to run these in a VP truck? Pushrods?

The wider face should allow a more aggressive ramp to be used-- much like the wider .904 Mopar diameter allows a more aggressive ramp than a .842 Chevy lifter or a .874 Ford lifter on gasser V8s.

So is anyone grinding a cam that can exploit the advantages of these tappets? You could get more "area under the curve" and better breathing for the exact same adv duration and lift..
