need 2F casting number help

Apr 16, 2002
So. Calif. (Moreno Valley)
I'm building a 2F from an FJ60 for my 1980 FJ40. I will post a build report on this motor at a later date. I wanted to find out if someone can help me ID the casting DATES for the block and head.

The block is cast with the number 61014 and a casting date of 50917

The head is cast with the number 61040 and has a casting date of 0731. This head has the extra late model bolt holes for the 3F manifolds.

Any help IDing the casting dates woulkd be appreciated.
