Humbucker Performer Kelly

I have old humbuckers from the Kelly Performer PS6T model, which I once removed, I don't even know why. are these ceramic magnets? would this be an improvement for my js32 king v?

I found information that these are J-70 with low signal. I think I'll stick with the original JS32 humbuckers
