I'm putting a Triumph Spitfire 1500 engine together, and the fuel pump I
have requires a spacer.  I've lost the studs that were on the car, and a
5/16-24 x 1-3/4 stud is scarce around here.

I can easily get a 5/16-24 x 1-1/2" bolt which should have the same
effective length so as not to hit the camshaft.  Is there any practical
difference between a stud and a bolt in this application, other than the
slight challenge of keeping all the parts lined up while I get the bolt
started?

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.
