They're either spline or Torx, the two are different. Mine were M10 spline, not sure of the Torx bit size but it's going to be something like T50. Might be worth popping the cam cover off and checking which type you've got.

 

Also, I think the Torx bolts are stretch bolts (not re-useable) so possibly better to buy 10 new bolts first and then get a suitable bit for them.

i also believe you have to tighten them differently. Think one is angle tightening and the other to specific torques. I think i did mine wrong but doesn't seem to have caused a problem so far and that was a while ago. Check the supplement part in the haynes book if you have one.
