I dont agree, my lash is only .016 and .018 hot ! A lifelong mech. and machinist, engine builder friend told me , 006 titer lash "cold" on alum. heads .
I read that toyota said the same thing -----------------thats the way I`ve been doing it for about 10 yrs now .
I f someone followed ur advise on alum. heads ,w/ a titelash cam , they`d lose it for sure !
