I have been trying to obtain pics of the rear valve covers and still waiting cause they do not stock the 15 SHO valve cover and hopefully next week will have some updates,was able to confirm that the 15 SHO rear valve cover has an updated BAFFLE inside the valve cover,instead of having it on the outside as previous 13-14 SHO'S,guess i was right when looking at FoMoCoSHO's pics of the engine bay.Z
