FE's are a little different....

I would get the engine hot, then run the valves again with it off. Set the intake valve when the exhaust valve starts to open, then set the exhaust valve when the intake valve starts to close.

Get to zero lash, don't worry about the pushrod being able to spin, but look for axial play and eliminate it. Once you've done that, go one full turn on the adjuster, then go to the next one. You will need one full turn to get the correct amount of lifter preload on an FE.

With solid cam all aluminum engines, lash grows about .010"-.012", so with that frame of mind, your preload would change by that amount.

If you run the valves that way and you still have a little noise, I honestly wouldn't sweat it. Some cams are just a little noisy. The Comp Cams Xtreme Energy and XFI lobes have a little ticky-ticky to them....
