Not to keep rubbing salt in the wound, but I bought a complete engine gasket
set (everything!) from AutoZone.  It came in two large FelPro boxes and cost
<$40.  And, they had it in stock.

I bought the FelPro from Advance Auto and it cost $18 or $19. I think the
whole FelPro Head set was about $40, but I couldn't see spending the extra
