lifter clatter

do they all spin the same?hughes told me that when they spin lightly thats 0 preload about 1 turn of the adjuster adds .020 preload and thats minimum..040 is goal.oh by the way mopar doesnt have adjusters do they.lol.. i have found that comp cams has a noisey valve train with their fast ramp cams too. i changed to fel pro 8553 head gaskets and found today they are about .051 compressed not the .039 they say .it cost me amonth of grief and about $100 in pushrods as i had to get the 7.550 longer pushrods hope to have it fired up soon to make sure, so id check your preload on all your lifters first.
