Another Stuck Head

[rf900rkw]

On the old Jaguar XK engines the heads were always corroded to the studs. I would wind a sacrificial nut onto the offending stud, put an air chisel with a wide flat bit against a flank of the nut, and buzz the crap out of the stud. You are pushing the stud sideways in the head hole. Try different angles and you will eventually find one where all that corrosion goo comes oozing up and out like a play-doh press. Hopefully this technique can be adapted to the A engine.
