I heard if you get stud girdles you don't need to set valve lash, true?
not true --- a stud girdle is a support that ties all of your rockers together so the individual rocker studs don't shake from high rpm harmonics ( springs trying to slinky causes studs to snap off with out a girdle ) with a racing roller for the most part must be used - not a street thing - yea you could bolt it on but it wont do anything for you --
hyd lifters take up small changes that go on in the valve train from wear -
solids need to be re adjusted so as all the starting points for correct valve openings are the same as what the cam company ground the cam on - meaning the intake and or the exhaust track tuning will be out of sink and performance will be down if the adjustment is off -- race cars might adj valves before every race chevy street car with a small solid every few months depends -- jz
