Who wants head?

I've got a head with the following casting numbers:

056 103 373

Can anyone ID this or tell me where to go for info?

Thanks,
Rory

Here I was thinking this thread was going to be one of those SPAM porno posts especially when looking at the name associated with the thread (your sig.). Nice title Rory. LOL

what are the two letters after it, or could be just one?

I don't recall seeing any letters. I'll have to take another look at it.

Dave, if you are looking for the porno, PM me and I'll tell you what I can :D
