Just wondering what you guys are using for a head cooling mod. I have the blower off and I'm looking at the Evenflow or the APS/Invictus model. Anyone have either of these?

the left side head between no 7 & 8 can get too much heat in some cases and can cause some major problems...My understanding in that this was a problem with the early '03 Cobra's....

The cooling mod just bring some cooling relief (antifreeze) to the back of the head area to keep the temps down....here's a link: http://www.lethalperformance.com/03...2511/even-flow-gen-2-head-cooling-mod-p-16947

That's what they say^^^^^, though I've heard some say the problem is with both years, 03-04. I haven't seen any concrete evidence of this, but to me, it's cheap insurance!! I just ordered mine, it's similar to the Evenflow kit Lethal Performance sells, but with braided hose and better fittings. http://www.stangshiftergaskets.com/invictus_cooling_mod_instructions_sty-2.htm

Just some info to help those of you taking out the freeze plug for this mod....When hitting the freeze plug for removal, make sure you hit the front of the freeze plug. If you hit the back(nearest the firewall) it will hit a lip that's underneath and not let the freeze plug spin enough. There is no lip in the front, which will let the plug spin like it needs to.

I should have taken a picture with the plug out, but I didn't. There isn't a uniform lip around the entire inside of the head. It's on the back half of the head only. So when hammering that freeze plug, hit in the front(the 6 o'clock position if you're looking at it from the front of the vehicle).

Imagine the fitting wasn't there and the freeze plug was in...

Just completed that install on my cobra and I hit the plug right there. well it did not pop up and what a PITA it was to get out. I am going to put up a small how to install with a bunch of pic's for others that are doing it.

That's funny, I hit the back side and it didn't come out. It did spin, just not enough. It kind of sunk down it the hole and hit the lip. I have read that hitting the front of the plug works best, but I guess it might not matter where you hit that damn thing. If it wants to come out easy, it will. If not, get ready for some fun!!
I ended up scored it with a dremel, then took a tiny drill bit and drilled until it barely went through. I took a wood screw and screwed it into the hole, then I yanked on the screw with vice grips. I couldn't imagine trying to do this with the blower on...
