Modern Aluminum head question

[36tbird]

I have not pulled a head yet where I installed these so I cannot report on the success of my theory, http://www.stefs.com/bandb/products/...washerstep.htm.

My theory is that if I can keep the stud centered in the hole, away from the walls, then maybe removal will be easier. I used anti-seize and 50-50 mix also. BTW, you need a special bit to drill the heads for installation of the step washers. I drilled both aluminum and cast iron heads.
