    I am unable to find this information, but if you want to use the Ford model A engine as a reference which was built from 1928-1931, the lifter bore clearance is 0.0015".  Since both the Ford and Indian are from the same era, I would guess that the clearance is also close.  I don't know if this helps, and good luck.
