Is it a ticking or a tapping? Does it make the noise all the time or just sometimes?
I had a tapping that would come and go. My mechanic said that if it was a valve , it would make the noise all the time. If it comes and goes it's more likely a lifter hanging up. He said the only sure way to find out is to open up the engine.
My old motor had 12500 miles on it. It ran great besides the ocassional tapping after making a 1/4 mile pass. He suggested running a heavier weight oil, Valvoline coventional 10w/40 with a quart of Lucas Oil Stabilizer. That pretty much helped.
Check your header bolts, plug wires, plugs, just to rule out any other possibilities.
Good Luck!!

there really isnt an adjustment procedure for pedastal mount rockers. you can pretty much bolt them down and go
it could be a bad header gasket.
heres a trick. grab a small rubber tube, coupe of feet long, hold it up to your ear and take the other end and try to find the sound, when the sound gets its loudest in your ear it means your pretty close.
i though i had a bad lifter ones and a guy showed me the tube trick and it turned out to be a bad headers gasket. you might try replacing them if you havent before. its pretty easy.
