Came across a deal for these- one head from Amazon, one from ebay. both new bare castings. Now ebay seller has backed out and said it is not available and refunded my money. I have read that this head is actually just an EQ head Mopar is buying and reselling. Anyone know if this is the case? I am trying to figure out how to get a set out without having to spend $500 with Jegs for one single head. Thanks for any help.
