[BILL WILLIAMSON]

Alex, mine was stuck/seized awful, soaked, drilled studs, etc, no luck.
Bought a cheap oriental meat cleaver 1/8" thick at the top & tapered gradually to a thin knifelike edge. Sliced it into 4 wedges with a cut off tool. Being careful NOT to hit a valve, drove them into the head gasket packing at all 4 corners of the head. After alternately driving them all the way in, doubled them up in opposing corners & drove them in again. Worked slick & NOT even a scratch on the head or block. These slightly tapered wedges applys TREMENDOUS PRESSURE!
My 2 long front studs & 2 rear studs were totally rusted to the head, almost as if they were welded together.
On my other car, one stud was a bitch, it was corroded & stuck, but not rust colored, but a charcoal grey color as if something strange seized it, electrolisis???? or ??? Color was sort of blueish almost like it was welded. Couldn't double nut it, so I drilled a 1/8" hole through the nut & stud, ground the shank end from a 1/8" drill bit & used it to pin the nut to the stud and with a 6 point socket, screwed the stud out. As it screwed out, the whole head lifted! Once the head was off, removed the pin & drove that stud back & forth several times before being able to drive it out with a punch. What caused that is a mystery & it was only ONE stud that did that!!! And it was NOT the cable clamp stud but one near it on the R/H side. Bill W.
