water pump stud removal

I am interested in knowing recommendation for removing studs holding the water pump (to the engine, not fan clutch) to remove the gasket material and ensure a flat surface. The top bolt is so close it would not allow for razor blades. Are there any common solvents that would help -- acetone, goof off, wd-40? This process would be more reliable with the studs removed. The stud threads are so short, however, and the lock nuts I have are too deep.
-- would it be worth trying thinner nuts with a treatment of pblaster?
-- gasket surface with acetone / brake cleaner before glueing..
-- install studs with a high temp threadlocker ..
> thoroughly clean stud hole threads with pipe cleaner?

see pic for stud thread length reference -- seems 6mm studs risk breaking in more than one place ..

Put a nut onto the stud far enough that a second nut can be put on top of it.
Using a pair of wrenches, tighten one nut against the other one.
Then back the stud out by turning the bottom nut appropriately.
Suitable nuts are easily available, and you can grind them as thin as necessary.

I think acetone would soften the gasket but the evaporation rate may hinder that. I'd try some WD40 with a heavy duty razor blade and take my time as not to gouge the aluminum. I have a putty knife that I keep sharpened with my belt sander that works pretty good, but I have to be careful with it

a gentle touch with a screwdriver might be enough to get the gasket material cleaned off around the top of that top stud.

i would not hassle with removing the stud, if it breaks off you'll be in a mess.
