360 magnum ROLLER ROCKER valve LASH question

I ran mine at 1/2 turn, Lunati 234@050 hyd roller, OEM lifters. Hughes wants 2 turns because it's quiter (people complain about noise) and the OEM Magnum preload is around .060 - .080
When I set preload I use the up and down method to get to zero lash, and then go 1/2 turn. The MP chart worked for me also. Once you are set at 1/2 turn you can also mark the adjusters with a paint dot. If you want to add additional preload you have a reference point.
