The next time that I have any need to remove my manifold bolts, I will be replacing them with short pieces of threaded studs and matching flanged nuts.

I am always nervous, for installations like this, of the steel bolts buggering the aluminum threaded holes due to wear, accidental cross-threading, etc.

Removing the nuts is a far "safer" approach, with much less potential for damage.
