1G DSM headbolts in 2 bolt block girdle, and why they are superior (pictures) - 3000GT/Stealth International Message Center
I came across this a long time ago and bookmarked it. I don't know how common this is as the guy looks like a hack but he may of been onto something. I would never recommend re-using old head bolts in your block but some brand new ARP ones might be promising.
Basically the deal is that you can thread these in about 3mm deeper and still not bottom out, since you have more thread to grab you can tighten the bolt tighter. Couldn't this over compress the bearings or warp the girdle?
