That 235 head casting code was used from around 1956 to 1962.
To ID the date of the head (if you are interested),
post the head date casting code.
F0111B is an engine serial number
F = Flint, MI engine plant
01 = month = Jan
11 = day = 11th
B = type of engine/vehicle = 235 car engine with Powerglide transmission
http://chevy.oldcarmanualproject.com/chevyresto/58003.htmThat serial number contains no date information - it could be 1957-1962
That engine would have had hydraulic lifters.
