Hi Mike,
Here is a screen shot section of the valve lift curve graph. The blue line is the intake valve lift curve. The 360 degree position is TDC at overlap. If I set the cam to straight up in the program it shows .048" valve lift at TDC (360 degrees)
It was a 993 camshaft from an N/A car, not a turbo cam.
I have a cylinder head set up with the cam carrier which I use with linear and rotory encoders hooked to the "Cam Doctor" computer.
Your measured .65mm would set the cam slightly retarded in the engine. Going to 1.2 mm is advancing the camshaft. As with any engine build, you should check valve to piston clearance unless it is 100% original. And even then it doesnt hurt to check.
