Master rebuild kit engine 318 1968

[MADCIMA]

Hi folks, I have a doubt, but what is the difference between the 1968 318 engine and the 1970 one?
i have to get an overhaul kit, but they only make the ones for 1970, are they the same?
Thanks in advance

They are slightly different. The compression ratio was lowered in 1970.
