I have a 2014 Fatboy Lo with the 124 Hot Set Up kit thrown into it. (103B engine originally). I am swapping out the rocker boxes and covers to wrinkle black instead of the satin aluminum.

My question.... are the gaskets between the S&S Superstock 91 heads and the factory rocker boxes a proprietary item I have to get through S&S or can I go to my dealer and use the same gaskets my 103 would have used? Not sure about the seal/machining between S&S heads and OEM rocker boxes and just wanna be sure. The dealership gaskets are more readily available for me.
