You're positive it's coming from the head? More specifically the top or bottom?

You gotta give us more on here so we can help.. a 4.6 motor will still run with all kinds of noises..

how are your chain guides and tensioners?

it could be bottom end.. bearing of some sort

have you had it up on a lift and ran the car standing underneath?

Make a video and lets go from there.

ive run it on a lift and it sounds like its coming from the heads. it has only been since the heads were done. and it sounds like its coming from the back 2 cylinders on the drivers side head....

pull the intake and compare the guides. you could also have clutch chatter.

Gregor185 · Jun 4, 2011

wouldnt clutch chatter go away when u push on the clutch??u mean valve guides??

Willis_98GT · Jun 4, 2011

Clatter never goes away.

check the plugs and make sure one isn't loose

PI96GT · Jun 5, 2011

also if its on the drivers side head make sure you're egr is tight, mine had a problem like that

Gregor185 · Jun 5, 2011

good point ill try that tomorrow. the car runs great and thats why i have a problem thinking its something internal

If it was your chain tensioners it would be making a loud clanking noise

Gregor185 · Jun 29, 2011

well guys i took the car up to a local mustang shop and they think the noise is coming from either the valve guides or there was too much machined off the valves. so they said they wanna pull the heads but i dont have the money for that crap so its gonna have to wait till next year to get fixed! :-(

Ninety8stang · Jun 30, 2011

Since you said that the tick arose once you put the heads on kind of makes me think you could have a bent valve. I ended up bending the #1 intake valve with the cams im running and had a constant good tick but never had any performance problems. Could be something else to look into when you get it apart. Hope you get it tuned in and figured out.

Gregor185 · Jun 30, 2011

hopefully thats not the issue...idk what id do

*e hug* I almost called you to see what was up ith thecar. you may have tweked a valve a hair BUT if it is and the car runs good just run it man it wont urt

Gregor185 · Jul 1, 2011

yeah im gonna go pick it up tuesday and just drive her

Gregor185:

If a valve is bent, a compression test ought to show a problem. At least it is inexpensive to do and will give you peace of mind if the compression holds nicely.

HTH,
