Preload set between a 1/2 and 3/4 turns past zero lash and using the twist method to find when tension just starts(zero lash) just my 2 cents
setting hot is only done on solid lifters after having been set cold intially.
355: The bounce method is better then the twist. if you can see the top of the lifter the movement is best overall. You adjust hydraulics hot because its more acurate! Push rod ,lifter, valve stem,lash caps, rockers, rocker ball, rocker stud, rocker nut, cam lobes, etc When hot expand and all the expansion values added up can change your lash or preload from a cold setting.
You tube has a lot of bad info your on one of the best sights on the web for info!!!! And learning!!!! Hotrodders!!!!
