Default 5.0 VALVE ADJUSTMENT

Newbie a little confused

Could someone please help?
I have a 90 mustang gt. I have read eveything I can get my hands on to find out to adjust my valves. Chilton say to bleed down the valve then adjust them. Ford tech say you don't need to bleed the valves.What the deal? Do I need to or not. What is the best way to adjust them.?Chilton has you do it in 3 steps. Some articles say do it1 cylinder at a time. I just put a crane rocker arm stud Converstion kit on. Dose this change the way you adjust them?

Thanks for any help

if you put a stud conversion on your car the factory positive stop procedure can not be used.

If you converted from pedestal to stud then yeah, you can't use the factory procedure. You'll have to go by what the rocker arm manufacturer says in their instructions

Thanks guys

But do i still need to bleed down the valves?Crane instruction says do 1 cylinder at a time, turn the adjusting nut 1/2 to 1 turn after you having taken out all the slack (zero lash).

From whatI read....you start at TDC (#1), and you torque bothvalves down to 18lbs......

Then you turn your crank a 1/4 turn.....to the next in the firing order......torque them both down to 18lbs.......

Continue through the firing order until you are done.

I am not sure if this is right, but that is what "they" say. I did that with my a car and it is running GREAT! If anyone else thinks that this is wrong, please let me know.....
