One Pair of Glenwood water cooled log style risers designed to bolt to wet log manifolds. They sell for over $500 new.
They came off a 455 olds jet drive, but from what I understand they will fit other manifolds. These are the Large Risers (12" x 13"), that use a 4 3/4" round flange. The hose ends are stepped to accept 2 7/8" or 3 1/2".
