If you can get hold of the original VG Peak Bouldering Guide (the one with Ben Moon on the cover) then you'll find a top 10 list of overhanging problems at the back.
In reply to johncook-2: another vote for cyl, woodwell, the shelterstone at trowbarrow, bodwerstone, there's some overhangs at st bees, plenty overhanging caves in the peaks too
