Try taking a slightly larger Torx bit and hammering it into the head, 
points into the corners.  I've had about a 50%-75% success rate with 
this technique.

Make sure you've gotten all the fastners out, then, yah, it's just brute 
force.  The seals get really, really stuck.  As I recall, you need to do 
one side of the V6 than the other as it can't lift straight up because 
of the angles involved.
