So my 5.9 build is almost finished.
I was 5 minutes away from mounting the intake manifold. Then I decided to run a tap through all the holes to clean them out a bit. Well I'm on the last hole, drivers side, rear most hole. And I snapped the tap off in the hole.

If this engine is on an engine stand then take the 5 mins and pull the head, load it into your car and drive to your nearest machine shop. This is your fastest and easiest and best solution. I do this VERY often but even MORE often the customer has made it FAR FAR WORSE by breaking and mangling more stuff up--sometimes to the point of irreparability.
If you just HAVE to try it yourself then go ahead and try the tap extractor but I think they have worked for me about three times in my life. If they are Magnum style heads it may be difficult due to the angle and if your tap is a tungsten/carbide deal then the weld method may be VERY difficult. My go to tool of choice is a masonry drill bit and I sharpen the bronzed on carbide tip on a diamond wheel to a specific angle/rake and sharpness--this is a last resort before the EDM is employed.
