Head Cooling Mod

My personnal opinion is their probably overrated, but why not if your going to drop the tranny or remove the blower. The thing I don't like about them is your doing something that the factory could of but didn't. Why? Even when they were updating the cylinder head they didn't. I don't think the 05 heads do this either, so it would seem that Ford had a reason not to direct the coolent to another line flowing coolent. Do y'all think they could actually hurt the motor?

Your half wrong. The 05 head doesn't need one because it was revised in the head to be able to exit. The old heads had no were for the water to go but stay in the back and thats why there have been issues with head tick. Ford never knew about the issue until after the heads were already made. I have one and believe it is wise mod to do. I took the blower off to do it.

Both of my Cobras have shown clear signs that cylinders 7&8 take more of a beating than the other 6...coincidence? I have the mod on my Terminator now, so now what would be interesting is to see if people have looked at their cylinders (or at least the spark plugs) after X number of miles...


Also, seems like Ford did in fact change the '05 heads to tackle this, so I think the answer to the question must be YES.

They do have coolant passages for the 7 & 8 cylinders, cool. I was thinking that Ford just beefed up the problem area's and mad it more revilent to the hot coolent. I assume you can't see the passages unless you have the head off, right or wrong?

I don't think there is a difference on the outside. I could be wrong, but if you were to cut it in half you would see the new design. There is one floating around on the internet somewhere with the cutaway head showing the new design.

The mod not only applies to Terminators, but also any DOHC engine that is pushing a lot of horsepower. I have the mod on my 99 and feel it is a worthy mod not just if you are pulling the tranny (non-roots cars) or blower, but if you are planning on any kind of high horsepower and/or sustained rpms.

I did the lfp cooling mod when I installed my whipple. It was fairly easy, but the fitting that you have to hammer in was kind of hard to get in. I wouldn't do the mod unless I was taking the blower off anyway for a port or twin screw. I figure anything to get better coolant flow is good in my book.

The way it was put to me was that since there was no real way for the coolant to exit the back of the head easily, the coolant tended to get hot enough to cause a vapor pocket and that is when the problem arises. I have the LDC mod and it was installed when the headers were installed and the tranny dropped. I heard it was a pain, but I tend to run the piss out of my car when on the track and so far no problems with my heads. Would I do it by itself ... not unless I was really running the heck out of the car. For the street, I believe it really isn't needed.
