I recently pulled the 305 engine from my camaro. while pulling the engine, we put a bolt in opposite ends diagonal from each other at the two farthest bolts holes in the heads and strung a chain between the two. As you can imagine, something had to go wrong. One of the bolts snapped off flush with the top of the head. I dilled down into it and ran a tap down in it, trying to be able to turn the bolt out, the tap broke and now i cant drill it out anymore b/c the tap is too hard a metal. I NEED HELP! Any idea would be greatly appreciated. I figured i could take it to a machine shop, but i dont want to spend the money if i could do it myself.

 

I've done that before....breaking off a tap. When I did it, I used a Dremel tool with a diamond tip bit to grind the tap out. One question....why did you use a tap and not an ez-out?

 

weld a 1/2"nut on the stuband use a wrench to get it out
