Hows it going my Stang buddies (haha)?
Anyway I am going ALL-OUT on my engine, an I'm buying these for cylinder heads for my 02 Mustang GT: Patriot Performance 4.6L/5.4L SOHC 2V Stage II Cylinder Heads (01-04 GT) at AmericanMuscle - Free Shipping!. Now what I need to know is do I need NEW rockers, an lifters? Or can I use my stock? Or do you guys recommend new an better rockers, an lifters? An can I have URLs of websites with the exact pistons an connecting rods for the stock block. It's going to be N/A for a couple of years but eventually F/I, so I prefer forged. But want the BEST compression the can be used on both. An do you guys recommend that I bore it 30 over?
I have a lot of money to work with so money isn't a question. Thank you guys SO much!

- Dave

Where are you located? I would suggest you find a reputable and knowledgable local engine builder to work with on the engine build.

I would skip the patriot junk. For the money there are better performing options out there. I would talk to nick at Modular Head Shop about your goals and he will steer you in the right direction. Modularheadshop - MHS

If you are truly going all out and money isn't an issue, skip the Patriot heads and go with some ported Trickflow heads.

Trick Flow® Twisted Wedge® Track Heat® 185 Cylinder Heads for Ford 4.6L/5.4L 2V: TFS-51900004-M44 - trickflow.com

Set them on top of a new Boss 302 shortblock with a forged stroker rotating assembly and some flat top pistons.

Shortblocks
I was actually looking at doing something like that. But then came to the conclusion that I want to bring the 4.6L engine to peak power without F/I. I was my 02 Mustang 4.6L to stay just that. An not have a different engine in the car. (I had a guy in a 03 Mustang pull up next to me an tell me that he had a Supra engine under the hood... So I asked "So why exactly would you have a Mustang body?... Just to say you have a Mustang that really isn't a mustang?" He couldn't answer. Hahah)

The new Boss 302 engine is still a modular engine, and all of the parts from your stock longblock will bolt right on. It's basically just a 4.6L engine that has been redesigned by Ford to make it stronger and run cooler (with the added bonus of being 5.0L displacement). Couple that with a stroker assembly and you're looking at 5.3L of displacement. No one would argue that putting this motor in is anywhere near as sacrilegious as putting a Supra engine in. lol

Whether you decide to stick with your block or not (boring it will increase the displacement slightly, obviously), get a better head than the patriot. Both heads that have been linked thus far will work on your current shortblock.

Those heads are for NA applications.

I will agree with that! :D Uhm, Im looking at the trick flow heads, which would be best way to go 38cc or 44cc? I want to favor torque the best I can But also add good horsepower.
P.S. I can't tend to find prices on the Trick Flow...? Any help?
P.S.S. Should I bore it 30 over?

If you're going to stay n/a, you could do 38cc. If you ever want to go f/i, the 44cc will be a better fit as it will lower your compression ratio a bit. Here's a link to the 44cc one.

Trick Flow Specialties TFS-51900004-M44 - Trick Flow® Twisted Wedge® Track Heat® 185 Cylinder Heads for Ford 4.6L/5.4L 2V - Overview - SummitRacing.com

Boring these motors isn't going to gain you much in the way of power. If you're tearing it down anyway, you'll want to bore it out some (say 0.020 over). If you go 0.030 right off the bat, you won't have any room to play with if something should happen in the future and your cylinder wall is damaged for any reason.

That price seems a little ridiculous. I would like to save SOME money, haha.
I was looking at this though: Mustangs Unlimited - The Premier Source for Mustang, Shelby and Cougar Parts and Accessories
or this: http://www.mustangsunlimited.com/itemdy00.asp?T1=TFS5144+01
let me know what you think...?

Both of those heads are for push rod engine and will not work on a 4.6.

Oh wow I must have looked right over that! haha. They stopped push rods with the Modular 4.6, that was the whole point... think i would have noticed. haha. Damn... Any other websites with Tick Flow heads that will fit on my 4.6L?
I basically need a whole top-end kit, except cams... So ANY EXTRA help is WELL appreciated. Thanks again guys.

Instead of trying to mail order things online find a local shop with a good reputation to work with. You will save yourself a lot of time, money, and headaches.

Trickflow is the only head for the 4.6. The rest are ported amd polished stockers. You already have cams? To get the most NA your gonna need an aggressive cam and pistons to allow for the larger cam.

I have Comp Cams Stage II Xtreme Energy XE270AH Camshafts (96-04 4.6L 2V) at AmericanMuscle.com - Free Shipping! these as cams with the cam gears. Again referrals are appreciated. But they are Stage 2. Plus I was gunna go with JE forged Flat head pistons, an Manely H-Beam forged connecting rods....?

If you plan to run FI in the future, setting the motor up for max NA performance would not be the best option. FI motors require a different CR, different cams designs, etc. You need to determine your ultimate plans for the car.

How many miles are on the motor? If money isn't a problem, I would replace all valvetrain/timing components in the motor.

For heads, I'd go with fox lake, MHS or the new TFS heads. The TFS heads will unshroud the valves more from the cylinder wall. Nick really helped me out a lot in choosing a cam for my build as well.

I wouldn't bore it out unless you need to, especially if you plan to go FI. The gain in boring it out is minimal when compared to just increasing the boost.

CR is dependent upon what type of FI you go with - twin screw, centri, tubo etc.
