Okay im confused & need lined out. I have trick flow heads & cam & harland sharp non adjustable rockers. The rockers did not come with instructions. The book says tighten certain ones to 22 & online it says find top dead center of cylinder & tighten both down evenly to 22ft. & other people say zero lash & half turn more. So someone please help.

 

zero lash and 1/2 to 3/4 turn is for adjustable rockers. torque yours down when your lifter is on the base circle of the cam
