non adjustable rocker arms and EOIC
EOIC comes into play when dealing with aluminum heads. If you are not at bottom of the cam lobe than you are torquing against a loaded valve spring and run a risk of pulling a stud thru the head. This is the only reason. Hyd lifters will pick up the slack.
If you have iron heads you can torque the rockers at any lobe position
This is a " BMP" Best Maint Practice.
