Mark,
I see that you are getting different opinions on this, but my recomendation  
is to ALWAYS prime lifters. Here's why. There will be no oil going to the 
rocker  box from that lifter until it is full of oil. Now I know that there are  
five other lifters supplying oil there, but maybe this one is supplying oil to 
a  specific portion of the rocker box and without it doing so for a while you 
could  be wearing something up there. I don't agree with the no prime theory 
since you  want to get oil up to the rocker box as soon as possible after 
starting the  engine. Priming is required in the 65 shop Manual and for sure causes 
no  problems. So why not do it and be safe.
 
You can easily prime a lifter by using a trigger-squirt can with the tip  
inserted into the side hole on the lifter to force oil into the lifter. Soaking  
lifters does nothing to prime them.
 
Also I don't recommend trying Chuck's method of looking for oil to come out  
the pushrods. The problem here is that oil trying to leave the lifter and pass 
 up the pushrod REQUIRES the inertia of a lifter in motion. If the lifter is  
stationary (eng not running) then the oil pressure just forces the metering  
valve up against its seat blocking the oil flow to the pushrod.
 
Take a lifter apart and see how it operates.

Bob Helt
