And that's why I still stand by my statement that the original specs can't be in a reground cam.
Either the lift or duration will have to be changed.

Yea, I said that wrong. The total cam height would be the same (nose to heal). You would still have the same lift, the same duration, the same cam profile. The lobe heal is just closer to the cam shaft base circle which would make the valve clearances greater. This is usually easily made up with adjustable lifters/rockers.
