stock heads you'll need the ford shim kit. only other way is if you have a stud mount head and have adjustable stud mount rockers.
Actually I just took them off (to check the lifters) so do i neccsarily have to readjust them. I didn't seem any shims when i took em off.

The proper procedure is to be sure the pair you're working on have their lifters on the cam base circle (both valves closed). Rotate (clockwise) through exh. valve open/close, and then intake open/close. Once the intake is closed, they are both shut. Put the rockers on. Hand tighten til you reach zero lash - no gap on the valve stem end or the pushrod end. Then torque to 18-20 ft-lbs. while counting the number of turns it takes on the bolt. It should hit that torque between 1/4 and 1 turn. If it takes more than 1 turn, you'll need to shim that rocker up (.030" reduces about a 1/4 turn). If it takes less than 1/4 turn or if you can't reach zero lash, you'll need longer pushrods. If you kept them in order - put them back as they were - you should be fine just torquing them to 18-20 while the lifters are on the based circle.
cool thanks, Do you know if the hydraulic lifters (stock) in the 5.0 should leakdown at all? Cause only four mine do in about 2 hours.

should the stock hydraulic lifters in the 5.0 motor bleed off the oil they have stored up in them? If so should they they do it in 2 hours cause that seems really fast to me.
