I'd make sure you don't have a bent pushrod or bad rocker/shaft/pedestal. It's easy to do, just take off the valve cover, and spin all the pushrods. You will have to turn the motor over slowly until each pushrod gets the pressure taken off of it, then spin them in place and see if any are bent.

Check it as krewat says, if you think that you have a dirty lifter, I have put in a qt of trans fliud and ran the engine for 5-10 miles and then changed oil and filter. Trans fliuld is high in detergant. Also a weak spring on the fuel pump will sound like a lifter.

Is it one or many? Kinda like e pluribus unum... If you have one lifter that ticks, figure out (at idle rocker cover off with a piece of hose to the ear or with a hammer handle on the pushrod side of each rocker in turn) which one it is, and replace it.
If it is many, check that the pushrods are spinning while the engine idles. If they are all spinning, and you see good oil flow at each rocker, you can bet that you have stuck and dirty (varnish) lifters. You can replace them or take them out one at a time and disassemble and clean them. If the pushrods aren't spinning, your cam/lifters have worn out meeting spots, concave lifter bottoms, or worn out lobes. The cam and lifter meet at a slight angle, and the edge of the cam causes the lifter to turn in the bore until the valve is supposed to close. If worn, consider the condition of the engine to determine if you want to do more than a cam-job...

Seafoam
Seafoam Seafoam Seafoam!!!!! Put 1/4 can through a vacuum line. Then pour the rest in your engine. Did justice for my sticky lifter. I put that stuff in everything I own. My go kart, lawnmower, etc., if it would help I would drink that stuff.

Let me retract my previous statement. There's two possibilities I can think of that are fixable and aren't broken parts.
1. You're low on oil. If it's too low it can cause a lifter to start ticking. I dont think this is probably it though, as if you're smart enough to find FTE you're probably smart enough to check the oil.
2. Your oil pressure is low. If it's low enough (like hot idle at a stoplight) it can cause a lifter to start ticking. Stick a real gauge on there and see what the pressure is.

I struggled with hydraulic lifter tick for 10 years and tried every and all
external fixes and nothing worked. I finally layed down about 500 and my
mechanic pulled and replaced the lifters and push rods and engine is quiet
as a swiss watch. According to him oil and crud issues may be part of
the problem but the main culprit is that the lifter spring just gets tired.
The archives on this board are full of this problem...good luck!
