I've prepared a couple of engine blocks (at least) at this point in my life. Yunno - gutting the block out, measuring all the parts, finding out how bad the engine rebuilder is going to cut into your wallet to make it "right."
Previously I have struggled with removing the head studs. I've used pipe wrenches, two vise-grip wrenches held alternately, a reamer wrench (those sharp hardened square openings bite very nicely into softer round stock if you choose your wrench size properly.)
I've done the "tap-tap-tap" on the top of the stud while under torque. I've done the two-nut method both with and without an impact wrench. I've used all manner of penetrating oil AND once even heat - which I don't recommend.
And I've broken a couple of studs in my life.
Yesterday I received my Ares Stud Removal Tool and today I took it for a test drive. On the block of interest I had carefully removed four studs without adverse incident by the means above taking about an hour to do it - but I didn't anticipate removing the remaining 10 studs in under 5 minutes!
Gosh - having the right tools makes ALL the difference.
I chose the Ares tool because it was advertised to be used with regular wrenches or an impact wrench. I can tell you don't waste your time trying to use the tool with a regular wrench - the impact wrench has it ALL covered. Including getting the tool off the stud once it is removed. (Besides the impact wrench you'll need a 1-3/8 open end or adjustable wrench.)
Here' where I got mine

So nice. And I hardly even got my hands dirty!
Definitely a "keepah!"
