Removing Stuck Heads

How about one of the spot blasters? The sandblaster with the rubber head that just does one spot. Hold it over each stud to clean then use penetrating oil. I have one I bought from Eastwood many years ago and it does great on those pesky pitted areas.

You're on my line of thinking....I was wondering IF you could get something like a "holesaw" just big enough to fit the stud and just run it to break the top 1/16 or an inch or so of the surface of the head to help promote getting the penetrating fluid of choice further down into the hole???? Usually the area that gets the most oxygen is the "most" corroded so IF you can break the surface THEN you might make more progress. ALSO the little that was cut on the heads you could chamfer with a countersink and not damage the potential of saving the heads
ALSO, I wonder IF you could use an air hammer and hit the studs from the top and sides a few raps to "vibrate" it enough to maybe loosen the corrosion OR at least help vibrate penitrating fluid deeper????
 
maybe make a threaded cap or put a nut back on studs and hit it with a air hammer all around the sides a bit to bust up the corrosion ?

You and I are on the same wave length as well, see the last part of my post above yours!!!!
 
On a lighter note: Yer gonna hafta get a little more aggressive to get this accomplished rockfla! Big hammers and chisels are your friends. A few years ago I was given a pile of flathead parts with the stipulation that I was required
to "take all of it". Like the song= "I'm so excited, I just can't hide it, I'm about to lose control and I think I like it." Included was a 21 stud complete engine with aluminum heads. Whoa, no head nuts and the heads were on the wrong sides. The owner of the parts had a couple knuckleheads remove the heads for him. They had pounded wedges of some sort between the block and heads. Not only were the heads toast but the block had deep grooves from the surgery. Almost all of my treasure hunt ended up in the scrapyard.
 
A very thin hole saw that will go over the stud and cut the corrosion , my father in law told me that was how it was done back in the day.
 
I have made 'off size' hole saws by kerfing down the side with a cuttoff wheel and squeezing it smaller with a worm drive hose clamp. Still pretty thick for this. Alternately, have it chucked in a drill, spinning against a bench grinder or spinning in a drill press and hit it with an angle grinder. You'll lose the set but won't matter at depth yer going.
