As a side note, Porsche used two or three different timing specs for their SC/ Carrera cam, right?

I have heard that the factory used different cam timing specs for the SC era engines. I think it was just the spec for setting of the cam timing that they changed, but I’m not sure of that. I think I read it in Bruce Anderson’s book.
As for the centerline spec for your cams, if I’m not mistaken you can calculate this if you have the intake and exhaust opening and closing event specs, which I’m sure is published for factory and aftermarket cams. Or find someone who has a cam doctor machine and have the cams measured.
