[Shop-talk] Studs vs. Bolts

[Douglas Shook]

I think you are good with the bolts. The worry of replacing studs with
bolts mostly is concerned with aluminum blocks where one could wear out the
threads if it required frequent removals. I do not think either one is a
consideration in your case.

As you said, a little trickier, perhaps getting the gasket, pump and holes
lined-up, but even that seems very doable.
