Ok, I have Edelbrock heads on my 351w with Comp Cams Roller Tip Rocker Arms and correct push tubes. I did the adjustments to the valves when I bulit the engine as the instructions explained.
Now that I did the first run up to temp and cam break in...I was told to re-torque the heads and reset the valves.

So, Heads are done but the lifters are now all pumped up. So do I need to bleed the lifters to do the valve adjustments? If so...how do I bleed them ?

Actually your initial adjustment was with lifter pumped up too. Once you start the engine and back off the nut till you have a slight lash, then return it to 0 lash your lifter is in the full, pumped up position. Once to turn the nut down you are pushing the lifter plunger back down to it's operating position. You would do your re-adjust exactly the same way.

wait their hydrollic(spelling sucks) lifters? they should have soaked in oil for like 8 hours before installation, but the Canadian is correct, once the engine cranks over one or two full rotations, they are fully primed.

Actually, Edelbrock said DO NOT pre-soak them before install. I know...weird ...
Any how I talked to Edelbrock today and they told me to fire it up, back off the adjustment nut until they start to clatter. Then tight'n till the noise is gone plus one quarter turn more. This is all done while its running.

Thanks guys, for the info and your time.

This is the same way I would adjust rockers on my small block Chevy's... This will be a very messy job unless you get an old valve cover and cut the top of it off...

I always tightened them 3/4 turn. I have seen reference to 1-1 1/4 turn. 1/4 turn seems loose to me but if that's what Edelbrock says I guess that's what to do.

Stock Ford was 3/4's of a turn but I agree, go with the Edelbrock setting.
