Hi!
I had the LPC17 core PCB for a long time, but ordered the LPC1769 only last week.
Yesterday morning when I wanted to solder the header I was surprised when I noticed (before soldering) that they don't match the one on the PCB...
After reading that post, I decided to solder them, remove the black plastic holder, and bend the pin to match the already soldered(about 1 year ago...) female connector on the PCB (The header on LPC1769 were soldered not "fully inserted", so I have enough room on each pin to bend them 2 times).
Here's some pictures :
