I show the C60Z-B as having Intake 38/86 degrees with .481 lift and the Exhaust as 96/48 degrees with .487 lift. If installed straight up, it would look something like this:

That cam was used in the '68 390 engine that put out 325 horsepower, but I also show a C6AZ-A in the '66 390 engine that put out 335 horsepower. There were also several weaker cams as well.
