[Healeys] spark plugs

[R. Price Lindsay]

I just installed Boach SuperPlus plugs.   The box says 7900. Is there  
a problem with these?  They have a "copper core plus Yttrium.". Don't  
really know what that means but it sounded good at the time.  I  
haven't started the engine yet so if I should change them...
