4.6L heads
I have a 2000 F150 with a 4.6L and only 98,000 miles. The exhaust manifold bolts were broke off in the head on the passenger side. They are not able to get them out at the Ford garage and will more than likely have to pull the head and machine them out. It doesn't make sense to me to pull one head and not do the valves on both while they are in there (yes, I have more money than sense). Is there a better replacement head for these engines out there that will make the engine run a little better or is it just the stock heads that will work?

Summit sells a nice kit if your looking for a little more power. (Trick Flow)
Cylinder Head Combos - 2000 - SummitRacing.com
Other then that,,,your stuck with stock or ported Ford heads!
Trick Flow make the only aftermarket head for the 4.6 and 5.4

Polish and shave the stock heads…. make a lot more power than most people think…lot cheaper than after market and you can still use reg gas.

Foxlake for one.
And I used TEA( total Engine Airflow)
They do a great job and might even be a little cheaper then FoxLake.
Check them out.

Don't know I'll need them but considering replacing my tired 5.4 gasser with a Ford long block in a '00 E250. Any better performance and/or MPG's I could wring out of the new motor would be nice.
This might be something to look into-------thanks again!

For a basically stock motor,
stage 2 heads and stage 2 cams is about all you would need.
Should get you somewhere between 40 to 60 HP gain.
I ran the stage 2 heads for a wile, but when I started getting up over 500rwhp I changed to stage 3 heads with a stage 2 cam.

I agree that the Trick Flow heads are over rated and stock ported heads will make more HP. I have a chassis dyno at work that has proved over and over that the Trick Flows never have made more HP than stock unported heads.

With all the talk of ported/polished heads and different cams I wonder how Mike at Five Star Tuning might incorportate a suitable tune into such a motor?
I don't need 500whp but a bump of 40-50 hp on regular gas would be great!
Interested thread so far!
