Who did NOT do the head cooling mod and survived long term??

You don't "have" to do the head cooling mod, of course, but it is usually recommended. Especially if you're in a convenient position to do it. Only a small percentage of '03-'04 Cobras have developed the tick issue, so in all likelihood you'll never experience it. And your mods won't affect it either way. All that said, if I was in your shoes I'd probably do it, just because it's a convenient time to do it and you'll have assurance going forward that you won't have to deal with an issue down the road, IF it were to develop. JMO.

My Cobra has 31,000 miles and gets tracked 2-3 times a year, 12 lbs. boost and no problem. My son's 03 10'th anniversary 125,000 street driven, no problem.
It's probably not a bad mod to do when the trans is out, but I believe most cobras are fine without doing it.

I've already posted in this thread...but I'll post again since I rolled past 26k last night...no hcm here. Late 2004 build with original untouched heads. And I hit 22psi multiple times again last night, this car just continues to rip every bit as strong as when I bought it 6+ years ago. This car has seen 22psi for a minimum of 8 years now, no head tick. Knock on wood lol
