I am in the process of pulling my old heads of the car. They are 186 castings, but I want to know how to read the date codes. Here they are and they are different.

Thanks. Most likely 68 because GM only made these heads for two years. 69-70.BS'er formally known as Rebeldryver

Re: sbc head date codes
While messing around under the hood today I finally decided to see exactly what my engine block came from. I've had this block for 12 years and never bothered to find out what exactly I had.
casting number: 3956618
According to info this block was made only in 1969. It could be a 302, 327, 350 block. Gee, that narrows it down. I know for sure it's a four bolt main from when I changed the oil pump.
The code on the front is this: T06I2HB
T= Tonawanda
06= could be day or month, I'm getting both
I= could be month
2= haven't a clue
HB= 1969 350, auto trans, 300 HP, 4 bolt main, A,F, or X body. What's an X body in 69?
