I tried to remove a few and I broke my craftsman T-40 bit without even making them budge. There is no way returning it 100+ times will help. What do I even do? They are STUCK. I'm trying to get the heads and manifold out so I can scrap the block.

 

I used an air hammer with a chisel bit to first, cut a slot in the bolt head, then lean the air hammer over striking the bolt in a way to turn it. Had them all out in abt 5 mins and they were all stuck.

Had to buy new bolts, but that's ok since I wanted to get rid of that TORX crap anyway.

I did this on an eng stand. Not sure if there would be room for this technique with eng installed.

 

i had 2 stick when i removed my manifold. first one i got out with just a lil heat. second one i took a dremel to and cut the head off of, then i replaced them all with hex head bolts

 

Well Im scrapping the block so dremeling the torx heads off shouldn't be a big deal then. Do the bolts go into the heads? If so then I really need them out.

 

well if you dremel the head off, once you remove the intake you will have enough of a stub to put a stud puller on it and remove it
