<VV> 444 FF AC Spark Plugs

[movair at aol.com]

 Hello all!


   I have almost four sets of AC 444 FF Spark Plugs, to include eight 443 FF plugs. For those not familiar with them, there are eight to a set, the box is black and depicts a man waving a "checkered" flag. Even the plug has a checkered flag on it. Anyone out there know about these type of spark plugs that can give me, (and others who are less informed), the lowdown on these plugs? I'm curious as to if they were used in actual racing applications, in Yenko Stingers, or whatever.


   Thanks for any info!!
