[Lupin..the..3rd]

No, not P-car related. I'm installing a set of ARP head studs in my diesel VW. (It'll allow me to turn up the boost a bit more without worrying about the head gasket. I'm running 1.2 bar now... 1.4 bar here I come! )

These ARP studs are a work of art. The nut threads on with a smoothness I've never felt before in a fastener. I thought it was a lot of $$$ for some fastener hardware but now I see why.

Yes, I know the box says "Ford Cosworth / Sierra". ARP actually doesn't make a set for the VW TDI engine. After doing a bit of homework, this set is exactly the correct size, length, thread pitch, etc and others have used them in this application with great success.

My question to the dorki collective, is about the torque method that ARP recommends. They say to torque them to 60 lbs, then loosen. Repeat that five times, but torque to 80 lbs on the last time. What's the reason for this re-torquing each one five times? Seems a bit excessive, but what do I know. Any thoughts on why they would recommend such a procedure?
