On my website there is lots of cam profiles.
I had thought I'd written that the profiles were plotted without any reference to the cam keyway.
Instead I had used the tools "lifter" to sit on both intake and exhaust lobes to the exact equal lift. The makes the profile with the cross over to be very close to 360 degrees or "TDC".
The cam timing is normally set as 10 chain rollers between the timing gear gear marks and valve opening timing can otherwise be measured and altered using well published procedures..
