Spring identifacation Mabey....

Ok, I know this may be a long shot to identify these springs. I was told buy the guy (local old mopar "guru") that built these heads that these are factory 340 springs. I am installing stainless steel roller rockers and am having issues with the spring just barley hitting the rocker. I also have a picture of the contact pattern. They are a litte outboard so to correct this I am going to have to lower the shaft right? Sorry for the picture quality the garage is a little dark.
