[TR] Copper head gasket: Which side up?

[TERRY SMITH]

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.
