Ahha! So there is an Allen fitting there that I need to deal with first. Thanks.

Dave - what I meant by sucking it out is that the 10mm socket leaves enough room for the pin to be extracted into the socket yet gives a very stable base against the head casting to push against. Basically I take a 6x50 fully threaded bolt, thread a nut all the way onto it with a washer and the socket next. Then I thread this combo into the pin until seated and then start tightening down on the nut. As the nut moves down it pushes socket against the head and pulls the pin out. The only problem has been that the pins are corroded in place so I'm striping the threads on the bolt a bit hence the overnight soak in Liquid Wrench.

I should get back to it this afternoon.
