I have no idea. I'd ask one of the big HP guys who have a shop and have had these things apart a few times.

The day the head comes off my truck is hopefully a long way away...

They say its in the works, also wanna thank Dusty for posting, great guy even though I never purchased anything from him he still took time out of his lunch to answer my questions, my gasket is stock thickness as not too much was taken off my head, they had the gasket made in like 2 days.

The spendy studs are made by ARP from a material called Custom Age 625. They are the only ones making fasteners from this super steel.

Data sheet from Carpenter (the maker of the steel) here:
