HDT-S126384 and P7P55D EVO

Intel changed the positions of the fastener holes,
so be sure that the fasteners line up with the
new hole positions.

From the photos at Newegg here:

... I would say NO, that HSF will NOT work
because the backing plate does not line up
with the LGA1156's fastener holes.

Specs say:
All Intel Socket 775 CPU
All Intel Socket 1366 CPU
(no mention of Socket 1156 CPU)

The Crossbow I5361 mounting bracket perhaps may bridge them together.

I really like the Thor's Hammer because it got a best of 2009 award by Tom's Hardware.

Yet that Xigmatek BALDER SD1283 looks really nice too.
