snapped three head bolts
well i was tightening my head bolt with a torque wrench and 7 of the ten bolts clicked just fine at 80lbs but three just kept turning stupidly i slowly kept turning all three probably 1-2 turns and then the middle bolt snapped. what should i do.
heres the order 1 2 3 4 5
........................6 7 8 9 10
2 3 and 4 are the three that never clicked and 3 actually broke. is it fine if i leave it alone or... how hard is it to remove. the bolt seems to have broken in the block.... this car pisses me off somethings.. just when i think i am getting ahead this always happens

Ouch. Sorry to hear bro. Is it still sticking out the head, your probably gonna have to drill them out possibly w easy outs but hard to say w that torque. Does it leak? Drive it around and check for coolant leaking into oil, will look milky. But yeah that's a big ouch. Take it to a shop w good metal work skills.

Yeah you could attempt removing it with an ez out. I would personally recomend having someone who deals with it all the time do it. Ive had this happen with dirt bikes before, but the ez out is a pain when its a small bolt. . . .you have to get it perfectly centered or it doesnt really work and plus the tools arent cheap.

I agree with ^^^ it's gunna be a PITA!!! One bolt broke in my block on my truck when I went to remove my IC. Tried to back it out (they make tools for this. We aren't the first people this happened to) that didn't work. Ended up drilling it out then re-taping the hole for a new bolt...

That is why I don't use bolts. Had that happen many years ago with a 7/16 ARP bolt in a 302. Went to studs and never had a problem. They can also be reused many times. I had to take my block to a shop to have it removed.

Yea, thats a ****ty place to be in. Gonna have to remove the head. Hopefully you will be lucky enough to have some of the bolt still sticking out above the block surface. Otherwise, its gonna be a total pita.
For sure, get some arp headstuds to replace it with. Whatever you do, dont drive the car. Gonna have a leaky headgasket which can lead to numerous other problems.
