Slick 60's

Hey Guys. I am trying to adjust the valves on my 1980 300-6. Am I supposed to torque them down tight and make any adjustments with the push rods? Or do I adjust them like I used to on my 66. Taking out the end play and then another 1/4 to 1/2 turn. Any help will be appreciated!!!
I have all the manuals for my 66 but I have none for an 80.


Thanks
