Going to redegree using an actual lifter.
Not sure on that one but probably pretty close either way. You can get a very cheap and accurate dail indicator from the net with magnetic base and arms to allow it to clear the valve. Its point should be put right on to the retainer.
This works pretty well remeber to use a little preload cause the first few thousands are not accurate off any indicator like this or even the lifter style indicators.

I use these on my mill in case i want to use the dail while the mill is cutting. I used these cheap ones in case they get trashed or filled with chips or oil.
