Re: [Chevelle-list] spark plugs

Thanks. I am not sure of the exact year of the heads but I was told  
early 1970s. They do take the smaller plugs.

Quoting Devin <[EMAIL PROTECTED]>:

John-  The question is, what year are your heads?  Chevy went to the small
"peanut" plugs in about 1970.  I would suggest you buy the plugs appropriate
for your heads and them gap them for the HEI, being about .050.
