Do any of you guys have any techniques or products you like to use when dealing with a really annoying stud? This is the last thing before the engine goes in and its holding everything up so ANY input is greatly appreciated. Thanks Guys

Go with a small drill bit first. And use cutting oils. After the holes are drilled .. use the SQUARE extractors. The other ones are junk.

I would just go to that GOOD and well-stocked tool-and-die tool supply store and tell them what you are doing. They should have that there in-stock. Post what they say ...I need that info because I have 4 sets of heads(8 or so studs) I have to do ! Oh .... Sears has those GOOD square extractors.

Heat to the stud also helps brake the crud loose on the threads. A few taps with a hammer after heating can help.

Clamp/hold an appropriate size nut in place and squirt it full of wire. Now it is a "bolt" and the heat has helped loosen it in the head.,.. sometimes. Other times the nut has just twisted off and I'm back to drilling, extracting. Good luck, Mike Bynum

I don't, but some do. never had luck with extractors. Usualy drill and tap , and threadsert when needed. $6.oo is a good price, don't think that will fly around, but I never checked.

If the heads are off (and I wouldn't try if they were on the motor in the car) Just drop them off, have lunch and pick them up. [IMG]http://i66.tinypic.com/pui5j.jpg[/IMG] Coming soon!!!!
