Only a few - all of them Works - LY valve covers were Mg.

Same situation for S20s.

Hi Alan , I missed the one last year . BH auction “  Mr. Watanabe memorial “ sold six S20 magnesium valve covers .There were some serious fanatics more then I expected.

Blue , the top red LY is owned by Mr. Akamatsu , me and him were a member of the group which were invited to the ZCON 2000 Las Vegas and 2004 Long Beach LA with our own Zs . 

Only very few people were realizing that is a special engine . Also I have told the Mikuni 50s were pulled from the works rally car in Safari.

I *LOVE* the crossflow head design.  Not sure why this wasn't used as the stock design.  

So cool.
