Headers with coil over K member

My buddy says that the TTIs and Doug’s fit pretty good. Kim
My 2" TTI`s are pretty close with raised port heads, but don`t rub anything, and even got the drivers side off and on last time w/o pulling the starter with it. Bought them used and straightened the flattened places from the previous owner, cut the smashed tubes out and drove an
1 7/8" trailer ball thru them , and welded them back in while bolted to a stock head. The chrome was coming off due to the header wrap he had on them, and that I replaced, ended up having them blasted and hi heat blacked.
Would like to have a new set of ceramic coated tho -----------
