Pink Milkshake seems to be more of a common (but still infrequent) issue but very preventable if poeple simply change their radiator since a radiator aging is the single reason for the issue while a cracked head can happen from alot of different things.
Cracked heads still don't seem like a regular issue from what I've seen with 10 years on yotatech and about 8 years here so I'm not too worried about mine at 171,000 miles.

Kevin,
I don't see any cracks and those heads look pretty good compared to my old ones.
Can you circle the damage in red, sorry maybe it is just my screen.
Btw, what are your plans? Refurbished head?

It is cracked right between the intake and exhuast valves there, hard to see in the pic but dead obvious when looking with the eyes.
The vehicle is in mint shape for 320k kms. And this is after hot tank. so it looks minty. minus the crack

Kevin,
At least you can do the work yourself
Have you gotten any quotes on resurfacing the heads, valve job extra?

I would never want to have to pay for this job myself! I am doing it myself as well, almost done actually, just going to finish it up on friday night. parts and labour alone cost around 800.00 so far, just to get a used head, have it surfaced, pressure tested, lap the valves, do a valve grind
adds up!

Does anyone believe replacing the head gasket prior to the 200K mile marker can prevent this from happening?

Just based on my experience, the headgasket was perfectly fine, so it wouldn't help to change it.

Aluminum heads + cast iron block = cracked heads/blown gaskets. Aluminum and cast iron expand and contract at different rates, causing stresses and warping. This is why proper cylinder head torquing and good gasket materials are extremely important. I worked at a machine shop for a couple years, and cylinder head failures are fairly common in aluminum/iron construction. Fairly common meaning more common as opposed to all aluminum or all iron construction. That being said, I still think most people will easily see 250k+ miles with no issues. And I think this thread has so far proven this, seeing as how very few people have reported problems. Just my $.02

I'm about the to do the TB and WP. Im also upgrading the Radiator to an all Aluminum 3 row for extra safety.
Just nervous now thinking the heads might be cracked.
Wondering if a compression test could maybe help, but im assuming not.

if i would have dont a cold compression test it would have definately told me which cylinder had the crack, but then at that point i wouldn't have known if it was a head gasket, or head problem
you never know till you take it apart.
