what year did the 848 head come on the 235 motor, and did it mattter what the motor application was? How do you identify the 848 head? I have a 51 or 53 235 that was an original powerglide motor and am wondering if i have an 848 head. i am installing a 60 261 in my 46 pu and would do the head swap for the added compression. thanks.
I just pulled an 848 head with a date code of K-1-3 off a 235 which makes it an early '54 model year I suppose. Not sure what the application would have been but that would be the first year for the high compression head I believe. You can identify these heads from the "848" in the last three numbers of the part number cast into the head.
