Ok everyone.
Took the head to my friends metal shop today. Tried a variety of methods to getting the stud out of the head on the '41 JD A. Here are the methods that we tried (after 8 tries):
1) Tig welded a washer and large nut onto the stud (probably 3 or four times). Tried both removing the stud while everything was red hot. The welds twisted off right at the stud. Then we allowed it to cool, tried turning a couple more times. The nut twisted off of the weld, but the weld stayed attached to the stud.
2) Tried the same method as above with a wire-feed welder with the same results - weld either twisted off at the stud or the nut twisted off of the weld.
3) Tried a mixture of the above two methods, also while heating the area of the cast with an oxygen/acetylene setup. Stud still wouldn't budge.
The question now is, am I stuck with drilling and tapping this? Seeing as I am going to have the head boiled/decked/etc., would it be wise to allow the machine shop to do the stud removal?
Maybe I should be posting this in the stuck and troubled, but I figured you all have been such a great help with this project already, I'd stick with it.

Up to about 1958 the dairy cows were fed hay with some turnips and after that grass silage was the main winter feed. That same year was the last in which flax was grown on the farm. Flax provided the fibre which w
