Just did a 71 340 Duster and used the washers on all the bolts and studs. The reproduction bolts are 1/2" shorter than the factory bolts! I used the originals because they were in good shape and everything worked out well.

The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.
