Default Morel Lifter preload??

Need to set the preload on my Link bar Morel lifters, couldn't get ahold of anyone to help me today, lol.

I have heard 2/3rd turn on a 7/16th stud is .030 preload??
Didn't know if this was true or even accurate??

I am not setting these hot, motor will be cold.

Any help is appreciated.

The newest Morel 'super' lifters call for zero preload. There is only .030" travel of the push rod seat.

Talked to Lloyd the other day and he recommened 1/8 turn after zero lash. Were going to try that.
