Greetings Evil,
When I try to identify casting numbers, I do a web search for the number plus the word "casting". Usually get quite a few results, though it seems there is much more info available for block numbers than for head numbers.
The 3835913 head was used on 54-62 235's according to one source. Other sources only list it under 54-55. It's the same head that's on the '54 235 in my '53 truck. Mine also has the numbers 918, 241, and 570, though I have no idea what those numbers mean. I'm guessing B37 is the head casting date (Feb. 3, 1957). Mine has B36.
RPO (regular production option) 723A refers to the paint color combination. I found one reference (
paintscratch ) that shows this number as "Garrison Gray" for 1960 trucks.
More info can be provided if you find the truck VIN, the engine serial number (stamped on pad to rear of distributor), and the engine block casting number (somewhere on the right side of the block).
It seems like you should be coolstepdad for doing a project like this with a 14-year-old.
