You might be right. My crane gold for my bbm came with springs, but since I was using them on old maxwedge heads with the aluminum stands, I made select fit spacers to get them where I wanted em. Took me a week to get my rockers set up properly.
I am beyond not knowing. lol I do know that all I remember springs on were some of the big block rockers, but that means nothing because there's been SO much out there over time, so who da heck knows? lol
