According to my paperwork we have the 145-4007 stud kit.

That's not exactly correct though, because we had to replace some of the hex nuts with 12 point.

I don't think that part number is specific to the World block so maybe I'm using the wrong part?



that is the standard ARP number for a wedge with b1 heads. i'm not familiar with the world block and though i can't say it's wrong for your application i would think it is.

looking at the 2011 ARP catalog all the PNs listed for both the KB and world (aluminum and iron) are listed for hemi heads

i would say it's time for a phone call to world to see what they require
