Seriously... omg... so frustrating...
After having my turbo off a half dozen times with the oem exhaust manifold cracking after welding as per cast iron welding procedure... then a cheap $200 header which cracked twice in less than 100 miles... so i buy the $700 LCE exhausr manifold... drive about 25i miles and blow the head gasket...
NOW i can't get the #6 head bolt to break... I've tried extensions, having my wife hold tension on it so i could hammer on the bolt... impact wrench...
still hasn't budged....
I'd really rather NOT twist it off... any viable options or intelligent suggestions? HELP!!!

That's exhaust side?
Try some heat.. Cut the head of the bolt off and worry about getting the rest out later.
Last resort is the tenfoot extension (gas pipe) on your breaker bar. And just twist it in two.

Ive had a few blocks come in the shop with a stuck head and bolts. We usually use a torch on the outside of the block where the bolt goes in. Carefully moving from the head of the bolt to the block back and fourth. You don't want to heat things up too much.. just enough. Also helps to have another person with a socket and breaker bar on the head applying decent pressure. We've always managed to get them out but we are a machine shop so theres that. Never broke one off...yet. Seen a lot come in broke off though.

penetrant is not really going to help you. The threads are in the block. I remember way back I had one stuck on an early 22R that came out of a field. I didn't have oxy/acyetelyne at the time. I remember using a 1/2 17mm impact 6 point socket and a breaker bar. I would come out periodically every hour or so and try to give it a whirl. I would try to tighten it slightly then loosen and eventually over a couple days I got it to break free.

I tightened all the other bolts back up....
took a 17mm box end wrench and put a real bind on it and going to leave it overnight... see if the constant torque might turn out loose...
An old outfield trick used to unstick tubing. .
I'll report back....

So these are the 2 bolts and 1 socket beat all to crap...i was holding the with vice grips while my grandson used a box end wrench and put a big bind
on the head bolts... then i positioned the bolt on my vice grips to contact the center of the head bolt and proceeded to beat the crap out of it.... trying to hit it hard enough to jar the threads or baked on carbon to let go... it worked!!! It was slow going but we got both of the exhaust side y head bolts out...

as soon as we got a tiny gap in the head bolt and the rocker assembly we started soaking it with wd40...
I'm so happy to get those out...

You said these were head bolts, just because they were inserted in the head I guess, I don't see head bolts here those would have a long smooth shank with a bulge near the head if the bolt...
These were holding your exhaust manifold on I would wager. A good example of why they use studs there, if the stud siezes the nut will still come off and you can get your part off.
Good job, creative and perseverant!

those dont look like head bolts. If those were holding on your exhaust manifold I would ditch them and order a set of actual exhaust studs. like the post mentioned above
