I am thinking of indenting it with a punch and drilling it and then using a extractor but i do not want the extractor to break so if you have done this before help guide me through it

I hand tightened them down and put the head on and they did not come through the head so i adjusted them (loosened) them so the would be high enough is that wrong maybe its the wrong kit help

they should come up through the head about ------- much

you only twist them down into the block until there are no threads left to go into the block. you could twist them down into the block by hand... they dont have to tight.. the nuts on top is what you tighten to 70-75 foot lbs

Yeah, this is a first hearing about an ARP studs actually breakin in half. They usually just tear up the aluminum threads first if anything.
