Lifter replacement - '86 4kq

[Steve Arbaugh]

Sage List: I'm in need of advice and suggestions (again).

One or two of the lifters in my 4kq are driving me nuts. I've tried the engine 
flush and changes, trans fluid, even prayed to the lifter Gods under a full 
moon, but nothing keeps these things quiet. Actually, they are quiet most of 
the time, then when they feel like making noise, they do. Happens when warm or 
cold, doesn't matter. The oil pressure has been verified to be good. There 
seems to be one primary offender, but occasionally two, that make the noise, 
but I'm at the point where I just wanna replace them all and get the thing to 
stop ticking. Is there some other elixer that I haven't tried that others have 
had luck with? 

How much of a job is this? Special tools required? What's the best way to prep 
the new lifters? Who sells the lifters (guess I better ask that too)? Any 
BTDT's would be greatly appreciated.
