Percent of lost lift due to 58 degree lifter angle?

So for the OP...did you want to know the loss of lift due just to the lifter angle?

That was the intent. Next, we have to look at the rockers and how they deliver that lift to the valve. Other factors I see are lift loss due to parts flex and compression. I see at least .010 lift loss just changing from checking springs to roller cam springs on m y drag motor.
