Noticed some of these rockers come with an oil hole drilled from the top side where the oil puddles , into the underside which oils onto the valve retainer , should i carry this modification out? , or just rely on the oil 'overflowing' onto the valve/roller tip?
Should i fill this hollow in the rocker before i fire up , although the motor has already been broken in before i tore it down , i read jessel reccommend removeing the restrictor on a fresh build , will this apply in my case?

Rather than bring my previous post back up , am i right in thinking the lash cold is .005 thou less? , ie , hot .022 cold .017.

TIA.
