Maybe a phisics expert can chime in but I think it has something to do with the shock value of that tool.
Always easier to work outside of the car, thanks for the compliment, good luck and let us know how it goes, ok? |

An impact wrench?
That one just scared me.
It would have been the last thing to think about for the risk of the bolts snapping off.
I assume that you will use it with a very low torque?

I've swapped gaskets on two 87 and no bolts snapped. I used an angled impact wrench, they are usually not as powerful as a straight impact wrench and apply an even load on the bolts. I set it on low and just let it work for a few minutes and the bolts slowly backed out.
Oh... I also soaked the bolts in PB blaster a few days before and just before I used the wrench I tapped (knocked) on the bolts with a hammer. Then threw salt over my shoulder, said a prayer... .... ... and everything else that could help.

Just thought I would update this thread, if you do decide to pull the head to remove exhaust mainfold bolts, you really need to get this tool, it'll save you from having to reset the valve lash, a real time saver and headache saver as countless posts about re-setting valve lash will attest to. The idea is that you can remove the pushrods without disturbing the rocker arm / valve lash settings at all.
Use this tool made by Lisle Lis 48500

Be sure to thank Partick for this excellent contribution. This is definitely the way to go when you need to drill out those snapped manifold bolts.

I wanted to update this thread with more information provided by our fellow members concerning drilling out broken bolts. The technique is to drill at low speeds, use plenty of oil, let everything cool down and use a good drill bit.

VICTORY IS MINE!!! I called up the local specialty fastener and tool shop and told them about my situation. They said the bit I need is called a GRT bit and if it doesn't get through it, nothing will so I stopped by after work and picked one up for under $5. That thing was BAD ASS! I went slow and used plenty of cutting fluid and that bit acted like I was working on mild steel. I even went back to the cobalt bits about 1/2 through just to see if it was something else. Nope. The other bits couldn't make a dent and this new on ate right through it (in about 1/2 hour with plenty of breaks for cooling and oiling).
I'll never waste time with anything else. These GRT bits (it's the style, not the company) are amazing.
Thanks for the help guys.

Thanks to cvillechopper and topcat, excellent stuff.

If you have time and really want to use good gaskets, try these:

I have has those in my 85&87 for ten years now, no leaks.
