Re: Intake manifold problems (Corvettelvr73)
I take my handy little dreimel tool with the reinforced cutoff wheel and grind a slot in the bolt. Then an impact screwdriver backs it out nicely. You may not even need the impact if the threads are in good shape. Try not to grind slots in your manifold when trying this trick as that would be a real :cry .

I usually use an EZ out, but be careful. If you break one of those off it's even more of a nightmare.
There is one in the last manifold that pissed me off. The easy out is still there and will never come out.

Re: Intake manifold problems (Corvettelvr73)
I feel your pain. Last fall I snapped a seized thermostat housing bolt. Tried the EZ-Out but it broke. I agree that they suck. I decided to pull the manifold so I could take it to the machine shop. When removing the manifold I broke one of the manifold bolts off in the cylinder head. When the manifold was off I decided my heads could use a rebuild so I went ahead and pulled them. Luckily the broken bolt problem stopped after the manifold. Now I have rebuilt heads, a shiny bead blasted manifold, and shiny new bolts thanks to the one broken manifold bolt. Hope you have better luck than I did.

Re: Intake manifold problems (BSeery)
I got this tip from my machinist as well as a friend who worked in Pratt & Whitney...to drill out those hardened tool-steel ez-outs, use a tungsten carbide bit. I dulled 7 cobalt bits (3/16" and harder than titanium) on one of my big block water pump bolts with a broken ez-out in it and only drilled in an eighth of an inch! I drilled the other one and one-half inches of the broken tool out with ONE 1/8" tungsten carbide Dremel bit and my dremel tool! I will never be without tungsten carbide bits again! :)
