small block head numbers

Here's a couple of pics, don't know what year, it was in the car when bought.
I’m thinking this is the probable number. They can be easily obscured by the rockers and springs, making it easy to miss the first and last number. Happens to a lot of us, even with experience. What year of 318 is it?
4323302 –318 LA-series small-block, 1.78/1.50 valves, Fast Burn, 56cc -65cc
Thanks Garret, my laptop would load pics, thanks for the info, helped a lot.
