Never broke one. I used to carry a drill bit in one air drill and an easy out in a reverse air drill and remove 100s of screws on major inspections. From little #6s to 3/8s. I have tap drilled a bolt that absolutely would not come out and then re-tapped by dental picking the first 2 threads clean so the tap would start in the hole correctly.

I was always frustrated with Fords and Rusted exhaust parts. I would get so mad I could not see straight. Then I started buying all the tools i used in the Navy quality tools mainly make a difference. And then the Rusted stuff stopped being a problem.

WD 40 is not a rust buster it is a water displacer. It is too thick to flow deep into a rusty thread area.

It is great when the truck plows through water, then you lift the cap spray with WD 40 and drive away.

They sell some stuff locally for Swamp cooler repairs it is even better than PB Blaster but like I said local. Mostly in the areas where swamp coolers are used in the SouthWest. It has a partner in an oil for the Swamp Coolers. They both come in a small bottle with a long extendable stem.

so far it has penetrated just fine and lubed the treads so I could break them. I only have one left on the bottom side that is proving to be a challenge just to get to.

on the driver's side, there is a piece connected to the manifold that flows to the exhaust tubing. I think that had something to do with the carb? :?

Driver' side? not on any Ford I know. Passenger side sometimes had a choke tube in the exhaust manifold.

When I did that on my '68 CS...
we tried every suggested means to avoid breaking the bolts...
it was much easier to cut off the headers with a cut off wheel pull the engine...
and get the motor on a stand...

All 8 of the top bolts off in the block... all 8 bottom ones came out easy.
Then we used a grinder to grind them smooth with the head center punched them and drilled them out just smaller than stock and rethreaded the holes to stock size.
I used stock Mustang exhaust bolts with ramp lock washers.. and lots of antisieze...
i can't stress the anti sieze enough...

They mostly used the intake heat riser setup. On the passenger side. I think they have a right side manifold on the left side. Where is the exhaust tube connecting to? :hmm:

I get a picture, I don't think that it could go on the passenger side without some serious exhaust tube fabrications.

That's what I did, but I had the fender off so the engine stayed in and I borrowed a right angle drill. I did brake a drill bit doing one of them, that required burning it out with a torch. It was fun. Posted the story here a couple years ago.

Dragon im going to try that drilling out the bolt before it breaks on my stubborn header bolts. You have posted lots of good info on broken bolts. Thanks,Brian.

ok, so I found out today that drilling out old bolt is too hard for me. has anyone ever just put on the new exhaust gaskets without only 6 bolts on each side?

You will have so many problems even cast iron manifolds will leak and fire track.
