Normally in this day and age of google and the internet there is no need to pay exuberant prices for any gasket, unless you need it NOW, and the only source is your local dealer. (has HIGH overhead)
If you google 11061-1121 gasket, cylinder head - for my smog head J motor, it pops at $39.21 +7.99 frt. on Partzilla. Further down, on the same google page, it shows an eBay listing for $15.99 with free shipping. Score! I just ordered this in anticipation of pulling my head in the next few weeks.

When I worked at a small mechanic shop while in college, my boss wanted me to use 3M "gorilla snot" to glue the cork SBC valve cover gaskets to the cleaned up valve covers in an effort to keep the VC gaskets intact if they had to be removed for valve adjustment after head rebuild run in. (he had all sorts of assembly requirements I had to follow) I have tried to stick these Kaw gaskets to the cover with RTV in the past, but they do not survive the same way the SBC cork gaskets did. However I have had great success with reusing them with a thin coating of RTV. The rubber composite on the metal gasket comes loose, so care is necessary to keep it as intact as possible.
