Yes that's correct u need to machine the lifter plates where the rocker arms sit coz u need to bring the rocker gear closer to to cam to Compinsate for the cam being machined ya cam machinist should tell u how much u need to have taken off

But I rang a head shop and they said that's only for a reground cam, where as I've got a street/race cam from crow and there's nothing on the spec sheet about it...

hey champ i have just gone through this i had to machine 30thou of the lifter blocks to make my engine quiet , i measured how much clearance the tappts had and machine an extra 20 thou to give the lifter some preload its an easy job to remove them and just get the machine shop t machine them down
my motor is quiet now no lifter noise
