Reading HR cam question - HELP!

Sounds like it's off. Intake should be .341 if it's advertised lift is based on 1.5 lifters or .312 if it's based on 1.6s.

I was expecting to see .328 on intake and .320 on exhaust to get to .525 and .512

If you are checking and the indicator is not in line with the lifter angle, you'll lose some reading from that angle.

Agreed, which is why I also read straight off the lobe

What you can do: remove the cam, measure the diameter of the base circle. then measure the highest point of the lobe; bigger value minus smaller value = lobe lift.
