Just a note:  I have made the mistake during earlier rebuilds of not using a 
succession of half-inch sockets bolted down over the sleeves to ensure each 
side of the cylinder has compressed the figure 8 gasket to allow the sleeve to 
be .003 proud of the head surface.  Invariably I blew head gaskets (okay, 
partially because I drive in what Listers describe as a "spirited" fashion).  
Since learning my lesson, I've blown nary a one.

Since you're at this point, just thought I'd mention.
