These were one of the first sets that Mike/AzCoupe at FordSix started to sell.
No more use for them since I upgraded to a full SS exhaust. Also not sure what to ask for them since everyone and their mother is selling headers for the small six now (seriously, berkeleying walmart pulls up a set https://www.walmart.com/ip/For-Ford-Mercury-I6-6-2-1-Design-Stainless-Steel-Exhaust-Header-Kit-Polished-Chrome-144-170-0-240-250-CID/163735144 )
$100 plus shipping? OBO?
