Anyone have an old LS1 head bolt I can have?

[ibjamin]

I'm changing head gaskets on an LS1 with ARP studs. I had to pull them out and I need to clean up the threads in the block. Most people take an old head bolt and grind a couple groove through the threads and use that as a reamer. The bolt is a M11 x 2.0 so isn't easy to find (none at work).

I'm in Sussex. Thanks in advance...
