Here is what we now know:

Currently the 2F and 3F-E camshaft carry the same Toyota part number.

This 1988 new features booklet (page 18 of the PDF, 122 of the booklet) states that the cams are different.

Mark W uses Delta Camshaft Part number KC859 with 262* advertised duration.

I also use this cam from Delta.

EDIT: I'll try to keep the valuable links up here.
