Re: sheared cylinder head bolt

ok, 'j cAT' just a question about the actual screw extractor or reverse drill bit.
I really like the idea of working with the cylinder head not only as a guide but since it would save me a lot of work to not have to remove everything to get to the engine block.
I picked up a set of JET '5 pc spiral type screw extractors' which gives me an assortment but really maybe I need to just pick a couple of the correct size.
Regardless, they are not very long, perhaps 2 1/2" long so really not gonna work very well if I leave the head on.
So is the reverse drill bit different than an extractor or can I get them in different lengths?
IE. the head bolt is probably 5-6" long (don't have one in front of me now but approx).

For the record I did buy new bolts. It's just been a long time since I used a torque wrench and I guess I was thinking it would be a more 'audible click' when I hit the correct torque. Plus the others made a sound so I just assumed just a little bit more would do it...
The bolts were from the same place I bought the felmar gasket so I'm pretty sure NA made.

If I re-read your post it would appear the first step is to use a reverse drill bit and then the extractor to remove the bolt. Correct?
