I've tried looking all over and not found the answer regard these headers. I'm looking at a set of Hedman Shorty headers for the 66 with the SBO 350. They look very similar to sanderson ones do you think they will fit the 66 without clearance issues? I know the long tubes are only from Kooks but theses have to be better than stock manifolds. Hedman 58160

 

They won't fit a 66, they are for 68 and up. You have limited resources for headers on an SBO in 64-67 A bodies. There was someone advertising a set of Kooks in the parts for sale section recently.
