Double check on the exhaust gaskets and make sure all teh bolts are torqued down properly.
Lifters do tick normally, some brand more than others. But if one lifter is ticking more than the others then it should be replaced immediately before any damage to the camshaft is done (if not already done) and then to the rest of the engine.
To narrow the lifter down, while the engine is running, take a long screwdriver (preferably, or any long rigid metal shaft) and place one end on the along head or bottom edge of the valve cover and the other near you ear (like along the soft spot right before your ear or on the bone right behind your ear). Move the shaft along the head/valve cover until you hear where exactly the tickking is comming from.
Be very careful not to scratch yourself or accidentally poke yourself. Or touch a moving object with the shaft.

I said double check the exhaust because sometimes with a new gasket, after it's been heat cylced a couple times needs to be retightened. (and you are instructed to by most exhaust gasket manufacturers). Just thought you may want to know.

well, the ticking developed one night after i was revving in neutral, i wasnt revving that high (same as i had before) but i guess a lifter was just weak and it messed up.

definitley double check the exhaust gaskets. I coulda swore i had a lifter ticking, turned out to be a leak around the headers.
Should it turn out to be a lifter, there has to be a reason it started ticking. If you throw a replacement in there without figuring out what caused the old one to go bad, its a good possibility the new one will start ticking as well.

i dont think revving in neutral would blow a exhaust manifold gasket would it??? well i'll see soon cuz i ordered headers the other day.
couldnt the lifter just be weak and thats what has caused it to tick?

Could be sticky lifter or loose rocker from the stud pulling out from your
over taching the rpms.
One other place to look.

So it started after you reved it?!?!?!?! This could be very, very serious problem here. I had the same thing happen once after doing a massive burnout in the rain. Once I let off I noticed a ticking noise. Stoppped by work, got a long screwdriver and did what oboebrian said to find where it was coming from. I pulled the valve cover off and found that one of the rockers had popped off the valve stem and was ridding on the keeper. This might be what happened on your motor, and if it is, YOU MUST NOT RUN IT!!! The rocker ridding on the keeper and cause it to fail, causing the valve to drop into the cylinder and have a little meeting with Mr.Piston. I recommend that you pull off both valve covers A.S.A.P.

well, its when i started hearing it. but i had revved it the same before and after the time i started noticing the ticking from. And its not the loose rocker cuz Ive put 1100 miles on it since that time i revved it and started noticing it. So apparantly its nothing thats needs extremely urget attention.
Sorta sounds like the adjustment nut backed off while you were revving it. It's an easy fix. Find a pair of old valve covers, cut the tops out of them and clean them, buy some neoprene valve cover gaskets, install the topless covers, start the engine and adjust them all. If it stops you know what it was. If it doesn't stop, then your engine will run better anyway and you'll know you have to keep searching. I back mine off until it just starts to tick and then slowly tighten it until it stops and then another 3/4 turn or so. I do this once a year. Engine (302) has 155,000 miles on it and it works fine. If the ticking is sort of light in sound (a rod or main clunks and is down low in the engine) and it in the upper part of the engine, and it doesn't get really loud when you drive it, it is probably a lifter. An exhaust leak will get louder as the RPMs go up while you are driving. It also sound more like a "phht" than a click. Plus you can run your hand around the manifold, not touching it because it will be hot, and chances are you'll feel the burst of hot air. You might have also collapsed the lifter. Sometimes changing oil will help. I'd adjust them first.
oil has been changed, even tried some marvel mystery oil in there. the ticking you cant hear at cruise, its only at low speeds or idle. I can hear the tick to at idle plenty and i can tell you its right in the top of the motor, left side. like it almost sounds below the second most left front manifold bolt. I figure i'll just drive it till something happens or till i get my new cam and lifters in 1 month.

No offence, but just cause you put 1100 miles on the car doesn't mean it is not serious (and why would you drive it when it making that noise). Look at it this way, if it is coming from the motor; then your motor is making a noise that it shouldn't make, and if your motor makes a noise that it shouldn't make, then something is wrong. Try and comprehend just how much speed and how much energy parts in an engine are moving with and you'll easily be able to see that even slight problems have horriable results. Like I said, just cause it went 1100 miles doesn't means it isn't serious. I've had cars come into work that have gone over 6,000 miles with a worn rod bearing causeing a rod knock, and others that didn't last past 100 miles. EVERY MOTOR IS DIFFERENT! Pulling off the valve covers takes no more then 5 mins to take off, and 5 to put back on for each side. I could be wrong here, this noise could not be coming from the motor. Just my .02

my dad used to be an automechanic and said that it sounded like a ticking lifter and that it wasnt that bigga deal. so thats why ive kept on driving it. if i take the valve covers off, dont i have to have new gaskets???

If your going to replace the cam anyway, you could use a bead of sealent on the old ones for a temp fix.
At least you would know what the ticking is from.

ps. If the stud is pulling out, you will know and maybe get those alum heads.
