   Brant ,
       It may simply be the way RWB supplies them now. Certainly not the same finish as originals and certainly not your fault. One of my early non automotive jobs was an inspector in a sheet metal shop where we did plating in house. I cad plated oil pans , rocker arms ( BIG mistake) nuts and bolts etc. Learned about hydrogen embrittlement the hard way.

For those needing both header type bolts, I have a few orphans of both types posted in pictures. 40.00 apiece yes they are original and don't show up too often. These have been in my stash for the past 40 years-

The short answer is you can soften the look of the zinc by spraying with a product like wire wheel cleaner for a few seconds. It knocks the shine off depending on how long exposed. There is however a learning curve on how long to expose a bolt to get the right look.
