Re: 02 gt

I don't see exhaust mods listed there.. Change out your mid-pipe and let it roar! Oh.. And be careful with SPEC clutches. I've not heard a ton of great things about them. I've never used it but just repeating what I've read constantly. They said if you do go SPEC route to buy a FRPP Pilot bearing and TOB.

Well then. My next path would be cams/intake manifold swap.

Then I'd definitely work toward gearing your suspension toward that power.. Definitely upgrade upper and lower control arms. Might want to look at some subframes, too.

^ this is a good idea , if you do the rear suspension I would also do new quad shocks and a set of drag radials

If you plan on boosting then don't do it.

Are you using forged internals? I would also try to find a set of "c" heads off a 03-04 cobra they flow a bit better then the "b" heads you have now , if you are doing FI change out your fuel pump, I would go with an avaitior pump with the kenne bell boost a pump set up

99 cobra's came with tumble port C heads. A port matching would be a good start.

Are there two different types of "c"heads?

The exhaust design was cleaned up and the port came to more of a square. The intake was also cleaned up in the bowl section. You can achive the same function with porting the 99-01 C heads.

I read there was a cooling issue with the driver side head can you resolve that problem with porting the head also?

it was because the eaton with all its heat and glory. what was happening was that some not all cobras where developing a "Tick". This was because the valve guide moved causing a loose exhaust valve, though drive-ability was not affected the issue down the line could become damaging. The valve guide issue was addressed with new casting. They where replaced on some but not all and can be told by the factory blue strip. People outside of ford came our with the cooling mod. as ford never applied a "fix" for cooling. When I ported my B heads, I also cleaned and de-burred all the oil and coolant supply holes in both heads and block.
So with that all said you would have to source the replacement heads. My personal choice is not to use the Eaton. Instead use a centri supercharger with air to air cooling. I prefer Procharger for ease of maintenance and installation.

The blue mark was a myth, only way to know is to pull the part number off the head

TSB 03-11-04 Engine - Mustang Cobra - Tick Noise From Engine - Cobra Vehicles Equippe

--------------------------------------------------------------------------------

FORD:
2003 MUSTANG

ISSUE:

Some 2003 Mustang Cobra vehicles with engines built before 11/1/2002 may exhibit an unusual engine tick noise that is present at all temperatures during idle. This noise may be due to valve guide wear in the left bank cylinder head. Guide wear manifests itself as a tick noise which can be heard at the rear of LH head, through LH catalyst, at the LH front wheel well and may not be heard with the hood open.
ACTION:

Use the diagnostic procedures listed in this article to evaluate the vehicle condition and replace the cylinder head if applicable. Refer to the following Service Procedure for details.
SERVICE PROCEDURE



NOTE:THIS REPLACEMENT CYLINDER HEAD WILL NOT IMPROVE OR REDUCE PERFORMANCE.

In order to diagnose noise, the following items must be checked.
Verify noise by placing a stethoscope on the back of the left head near the exhaust ports.
Verify that the noise is heard in the left side exhaust system (left side wheel well or catalytic converter, from underneath the vehicle).
Try to isolate the noise by canceling the cylinders, by unplugging the injectors one at a time (start with #8 cylinder).
Verify that there are no exhaust manifold leaks.
Check to make sure that the camshaft spacers are in place. If not, install cam spacers (per Workshop Manual Section 303-01C) and retest vehicle.
Check for proper cam sprocket bolt torque, retorque to spec listed in the Workshop Manual Section 303-01C.
Check for spongy lash adjusters (refer to Section 303-00 in the corresponding Workshop Manual).
Verify that the timing chain tensioner pin has been removed. If the above diagnostics does not eliminate the noise while the cylinders are cancelled, and the engine was built prior to 11/1/2002, replace the left side cylinder head and cam assembly with Part Number 3R2Z-6049-GA. Refer to Workshop Manual Section 303-01C for cylinder head replacement procedures.

PART NUMBERPART NAME3R2Z-6049-GACylinder Head And Cam Assembly - Left - Cobra Only

And those replacement head came with a blue strip.

Wrong.
Why don't the instructions say to verify if cylinder head have a blue mark?

so ford is wrong? Funny thing about the internet is you can read anything. But I tend to follow the publications from the company and engineers themselves. Now having worked a short time in a ford dealership can say the blue is real. Now you can order the latest casting thru ford racing. Which has no mark.
