  We propose a novel mechanism for exclusive diffractive Higgs production $pp
\to p H p $ in which the Higgs boson carries a significant fraction of the
projectile proton momentum. This mechanism will provide a clear experimental
signal for Higgs production due to the small background in this kinematic
region. The key assumption underlying our analysis is the presence of intrinsic
heavy flavor components of the proton bound state, whose existence at high
light-cone momentum fraction $x$ has growing experimental and theoretical
support. We also discuss the implications of this picture for exclusive
diffractive quarkonium and other channels.
