re. size of the socket for head bolts ???

[Swann, Benjamin R. (BSWANN)]

I think it is a 12mm or 13mm 12 point.

[  What is the name of socket type (it isn't torx, is it?) and size of the
  socket for head's bolts?  Is it available in local parts stores or
  dealer item only?

  Thank you.

I forget where I got mine, but your local FLAPS shoud have it.
