Honestly, I would say there's no appreciable benefit on their own.. Your stock Ford heads flow well and are just fine for now. But then again, it all depends on what stage NA you are currently at, or wanting to reach. Personally, I would only recommend these Stage 1 heads if you had FFRP Hotrod cams, Intake, LT Headers, and 62mm Throttle Body, etc...
And, please be aware that by staying NA with all this, you will probably max out at about 360rwhp.
Trust me, to save your self a lot of money and frusration ... save your pennies and go FI !!

I was just kicking around some ideas. Now it seems im leaning toward leaving the car alone and not doing much else. I understand why mods get so expensive....one parg leads to the next and the next and the next....its a never ending process, and a nevef ending drain on your finances. So i have a car that looks good , sounds good, i should be happy woth that

well DC its all about what you want out of your ride. ;-) If its just for street cruzin. Dont need to do much of anything to Enjoy it. Its a great car!!! If you want to do some kind of track time be it drag racing,Autocrossing,Road racing etc.. There are a host of diff. mods that can be done to step up the performance of the Mustang. And yea it can get $$$ depending what your Goal for the vehicle is. When you have a goal its really important to look at the whole picture so you dont spend $$$ you dont have to IMO. Good luck and Enjoy Cruisin. ;-)

I installed these heads when I rebuilt my engine and I'm very happy with them. The engine has a mild comp cam, Roush 1.9L supercharger (8psi), JBA shorter headers, cold air kit, 47lb injectors, 62mm throttle body and an SCT tune. It develops 435HP at the wheels and it's a fun daily driver.

It is my understanding there are two versions of the FRPP CNC Ported 3V Cylinder head.
First version part numbers are M-6050-N3VPA (left hand) and M-6049-N3VPA (right hand). These hands normally retail for around $950 each. These heads use OEM production size intake and exhaust valves. Complete specifications:

Second set are part number M-6050-463VP3 (left hand) and M-6049-463VP3 (right hand). These hands normally retail for around $1650 each. These heads use intake and exhaust valves that are 1MM larger than the OEM valves. Complete specifications:

Both sets of heads use the newer 08 – 10 “High Thread” style 16MM spark plugs.
I used the M-6050-463VP3 and M6049-463VP3 set in my Vortech V3 Si Trim equipped 4.6L Aluminator build and achieved 585 RWHP through an automatic transmission and cats.

Actually there's 4 versions of the heads.
the 2 that Scott2 listed and then the high thread versions of those which are similar but slightly different (IIRC the HI stage 3 have a smaller combustion chamber which should yield higher compression)
Mine are FFRP Stage 3 (IE large valve) but are the HT version and I got them at a great price because there's lots that don't want to use the HT heads so the seller lowered the price.
If you are getting them at a great price then check if they're HT or non-HT as they use different coils.
