    i'm installing block off plugs for the 2nd spark plug hole in a set of old fuel heads, what works best for sealing the block off plugs. copper washers? old spark plug washers?

    thanks

    washers

    I used the copper ones from a set of index washers from my chev. days. If you have a set of used ones then use them. I never use new washers even on my plugs.

    And keep am eye on them! I had those in the first Hemi I ever owned and they would start to loosen up. Never fell out (man that would be ugly) but just needed to be checked often.
