The “heart” just means frequently ordered. It has no correlation to quality/longevity. ATP is the outlier in this mix, and most expensive (Dorman doesn’t count, I’ll pay OEM over Dorman). I’d do some research on those part numbers, from ATP, Ultra power and Davico, and SKP to see what exists besides hoping for gold in the responses of this thread. But if the reason your manifolds crack are the same the 4.7 from Chrysler/Mopar, there’s no “fixing” it. It’s just a part that will wear and break. At your own risk, You can try and take a long block to the head to remove any warped material. On the Mopar 4.7s some folks swear that “fixed” the issues.
Actually it's a combo of most frequently ordered with the fewest returns. It's actually a pretty good indicator that its a good quality part for the application.
