One head looks to have been worked in area between valve and piston chambers. Got it in an estate sale of a former NJ stock car driver. Not sure why it was done or if Weiand produced different versions of the "S" heads it sold. There is no valve relief work done on either head. I could probably do the work but not sure how much material I can safely remove.
