Yes you need extensions and a new ford gasket is the best I would think

Get kooks use stock Ford gaskets. Macs I don't like had them on my old 99 Cobra.they also made.my car smoke.like.007's cars.something about the coating on them. Had bad reviews many years ago. Kooks wont turn color of rust. I love.my kooks.and come with the 02 extenders get the 1 3/4 one with the 3 in collector if you have the bucks.good luck!
