i am getting ready to start my 283 for the first time i bought a haynes overhaul manual and it said that to adjust the valves you go through the firing order and when both the lifters for that cylinder are flush with the lifter valley you see if the push rods will twist if they twist then you need to tighten the spring till the it wont twist and then go one more turn i did this for all the valves and timed the engin with the balancer will i need to adjust them when the motor is running or is what i did fine the book made no mention of doing it when the motor is running
