Porting V-10 Heads
I have looked to see if a thread like this was started and I didn't find one. If one has, I appologize now for starting a new one. I had just experienced the dreaded spark plug launch from one of the cylinder heads on my 2001 F-250. My brother-in-law is a Ford mechanic so we are going to take the heads off the truck and have all the spark plug holes fixed. I have 105,000 miles on the truck, plugs have been maintained, changed, checked, torqued, and one still blew. I want to keep the truck, that's why I'm fixing the problem now once in for all. I have a question, has anyone had their heads ported and if so, what performance gains did anyone see? From the apperance, these heads look real similar to the 4.6 and 5.4 heads in design. With all the mustangs, Lightning trucks etc out there being modded, I would assume some of this work could be a benefit. The truck is a every day driver but also pulls a 11,000 lb trailer quite often.

Good question!
In the past, I remember people saying a pair of ported "regular" 4.6L heads outflowed the PI heads.
The only thing I would do, and it's probably pretty expensive, is to get a junkyard V10 head and cut it up to find out just how much meat you can remove.
But don't go too big on the intake side, you'll lose low-end.
Port matching the intake to the heads would be another good move. (probably already thought of that).
I wonder if there's room for oversized exhaust valves?

Porting V-10 Heads
I checked out the V-10 head porting thing with a real good machine shop that loves Ford modular engines here in my town. They told me to go get a super charger. The reason, for the money, it would be the best performance mod I could do. Do to their work load the lead time would be 2 months so it would be best to find a good core set they could work on. Intake valves would stay the same, exhaust would be made larger. Due to the size of the heads and the work involved, $1600.00 was the price tag. This would get these heads in line HP wise with the 3 valve head flow. The shop told me to expect 40-50 HP increase. That's why for the money, get a super charger.

From what I have read on supercharging these engines I thought it would take about a grand or so for a used supercharger, then you would need larger injectors and some other mods (most likely a tuner). I was guessing in the past at 4k to supercharge a V10 but I could be completely off base. For $1600 my cheap self would even consider doing it.

I beleve comp cams makes a set of cams for the V10 but I don't know how much it would cost. New cams should give you gains similar to porting the heads.
For a gasser $1600 for 40-50hp actually is not a bad deal.
A new supercharger system for the 2V V10 will easily cost over 4 grand. A used one will be less, however a GOOD used SC will still cost a lot more than $1600.
With either the cams or head porting I'm shure custom dyno tuning would be needed for optimum power and longevity.

couldnt you just go to a junk yard or buy some used 3v heads from a newer V10?
THENN do a supercharger!

the three valve heads would be to complicated to convert to due to variable cam timing and other differences but if you figure out how let me know haha

Only problem about a SC for the V10 2v...is that they are NO longer available. The only option...is going used.
For a daily driver...the 91+ oct gas is going to kill! IMO...just stick with the V10 2v with fixed spark plug holes. Trying to gain all this hp and/or torque with an engine that has 105,000 miles...is just asking for more trouble.

Not disagreeing on how hard but I need every one to understand this...!
The 3V V10 do NOT have variable valve timing (VVT) or any variable cam timing
The DO have Variable Volume Plenum.... there is a computer controlled and mechanicaly actuated "Vane"/"Butterfly" valve inside the intake mainfold (Plenum) that opens and closes to adjust the intake air flow rate and volume to keep torque high under all sorts of variable load conditions......

Fredvon4,
We had a '98 Windstar with the 3.8L V6. It had a plastic intake manifold with both short and long runners. With a butterfly that would switch between the two sets of different length plenums based on rpm.
Is this how our 3V V10 intake manifold works?
Thanks,
RustyFuryIII

There's a lot of improvement with ported 2v heads and lots of room to port them if you have PI heads but none PI heads will only be able to match stock PI ones. Pretty easy to get 40-50 cfm with good porting and aftermarket valves 1mm bigger on both without loosing any real low end due to how bad they are stock.
COMP will NOT regrind the V10 cams but Crower will for about $300 for the pair shipped back.
Stock seats fit bigger valves fine they just need to be cut accordingly
You cant port match the intake manifold with the heads because the intake manifold ports are about 40% smaller then the head ports. They are for shear velocity not flow. 3v heads will not work in a 2v truck since the 3v uses more electronics and better valve timing tables youd need a ecu swap atleast and harness but by that point you would have been better off porting.
