more lifter preload questions

here is the background on this issue/question...

re-reading this, it seems to imply that I just torque the bolt down to 20 ft pounds and run it...

I have read things along these lines:

PRECAUTION: If you have an older high mileage engine that the lifters bleed off pressure (drain the oil out of). You can improperly adjust your valves. You need oil in the lifters to be able to get an accurate setting. If you repeatedly adjust the valves this way and they are still not correct, you probably have lifters bleeding off during adjustment.


please, more thoughts and experiences.

thanks,
Matt
