Re: Broken head stud
Here is my TRIED and TRUE method that I have used on several occasions. Use a mandrel guide for a 23/64 left hand drill to remove the broken stud without damaging the original 7/16 threads. I believe this handy tool is available from several of the parts dealers (Bert's, Snyder's) You will need to use these guides with the head back on the block. First pass is with a 1/4 bit with its guide and then go to the 23/64 guide with the left hand bit to finish removal of the stud leaving the threads to be cleaned out with a pick followed final cleanup with a 7/16 bottom tap. Take you time don't get in a hurry.
I've never tried Vince Falter's TIG weld washer system, but it looks good too.
Which every, DONT TRY to drill it out without a drill guide…
Good LUCK
