Jan ‘05 DC 9 Thread 4v Cylinder Heads
Extremely rare badass cylinder heads!
These are the highly sought after “DC” casted cylinder heads. If you wanted a set on a Cobra, it would’ve been a retrofit only. Ford Racing offered these as a performance upgrade only to our cars, however, they were found on the 2005 Lincoln Aviators as well.
I've had these cylinder heads since the beginning of this year. I was going to put them on my car, but all they have been doing is sitting in my living room. They have been wrapped up in a climate controlled room and I haven't touched them since I picked them up from Ron @ Fox Lake.
When I finally found an excellent pair of Jan ‘05 DC Casting Aviator Cylinder Heads, I knew I wanted a reputable speed shop to do some major work to them. To go all out and build me some built proof, major cfm breathing, cam loping badass 4v heads (cleaning, machining, porting, etc.). Out of all of the speed shops around, I narrowed it down to either Livernois Motorsports or Fox Lake Racing. After comparing the two, researching and reading reviews, customer satisfactions with products etc., quotes on pricing (which they were very similar). I went with Fox Lake Racing.
These are an excellent pair of heads for anyone wanting a phenomenal upgrade. I’m still on the fence honestly about letting these go. It took me 6 months just to find a set that wasn’t trashed or that had FUBRA cam journals. These heads come assembled with Stage 3 Comp Cams, Ford GT Supercar Followers, Brand New OEM Lash Adjusters, ARP hardware, James’s billet secondary timing chain upgrade, FRPP secondary timing chains & sprockets, and are ready to go bolt on. These are basically brand new, still has assembly lube, never been installed.
Complete heads with the following...
Comp Cams Stage 3 cams.
Comp Cams XE-R Supercharged & Nitrous Cams | 2003-2004 Mustang Cobra
ARP Hardware.
ARP 4.6L/5.4L/5.8L Camshaft Bolt (M12)
Ford GT Supercar Performance Followers/Rollers (x32)
Ford GT Supercar Performance Followers / Rockers - Set of 16
4.6/5.4L OEM Lash Adjusters (x32)
4.6L / 5.4L 4V OEM Lash Adjusters
FRPP Secondary timing chains, sprockets & driver side tensioner upgrade.
Cobra Engineering Billet Secondary Tensioner (Passenger Side) - it is well known that the factory passenger side tensioner has flaws.
Cobra Engineering LLC
I’m also, including in this sale the following.
FRPP Timing Chain Kit. (Only makes sense since from the FRPP kit I bought, these heads are using the secondary chains & sprockets from it.)
Ford Performance Mustang Camshaft Drive Kit Aluminum Block Application (99-04) 4.6L 4V M-6004-A464
Trick Flow Adjustable Crank Sprocket. (Which in my opinion is the ONLY way to go when using adjustable gears to get the degrees spot on.)

Everything included in this sale is brand new & assembled together by Ron @ Fox Lake Racing. These heads will rev to 8500 RPM all day long and were built to handle well over 2k rwhp.
Asking price is $6000.
Here is an invoice of what it cost me just for the machine/port work & the badass upgrade to the Springs, Valves & Seats.
This invoice does not include the price of finding & buying the Factory Heads alone, or the... Stage 3 Comp Cams, Timing Components upgrade, ARP Hardware, All New 32 OEM Lash Adjusters, Ford GT Supercar Followers/Rockers... etc. I put the links to the items of the things that I bought so you can see the price of those items. These are close to an $8,000 pair of cylinder heads.
