hi, the mopar 509 requires .028 and .032 lash for solid lifter. cams all have their own lash specs. follow them! BTW, set hyd at zero lash, + 1/8 turn. new style lifters don't need deep plunger depth. by setting at 1/8 turn, will not have lifter pump up at RPM. makes it like a solid lifter cam, old trick from way back.
