I initially posted this in my build thread in the Pig Pen, but will repost here for more input.
I have a 75 FJ55 with a 78 2F engine. I attempted to order PN 90913-0233 valve seals from Toyota Parts Deal and they canceled my order, saying they were discontinued and not available.
McGeorge Toyota has the 90913-02033 valve seals, and have shipped them out today. I look forward to discovering what I actually get.
One of the things I've learned from this part of the project is the moving goal posts that are Toyota Parts.
The valve seals that automatically come with the cheap Fel-Pro engine seal kit are the one piece rubber kind that belong on the 1F engine. Those won't work on a 2F, because the top of the valve guide isn't shaped correctly and the seal just rides up and down on the valve stem instead of staying stuck to the valve guide.
From my research, it appears the first version of the 2F valve seal is PN 90913-02030. These were replaced by PN 90913-02033 around 10/78. Sometime around 1984, the valve seal part became PN 90913-02048. I guess it's possible that other part number valve seals exist that would also work.
I have no clue as to the interchangeability of the three valve seal part numbers. I wish I had a good idea of how they differ, and why you'd want one over the other. Anyone out there a 2F valve seal genius?
