Pushrod Removal

[Nate's Alero]

Well, im in the middle of my headgasket change, got a few questions answered by calling some amodders, but still, when i remove the valve covers, and i remove the rockers, do i need to write down the amount of turns it took to get the rockers off?

or do i just remove them and then put them back on snug? im confused... and i would like to pind a pushrod puller, but i cant seem to locate one at any local autoparts stores, becuase i would not have to remove alll these pumps and screws / harnesses,

please help?
