How to get current height of largest element in a collection?

How to get current height of largest element in a collection?

I have a series of elements with fixed widths but  heights which vary based on content. 

I need to set all elements of like classname to the same height as the largest current one.  

So far, I have this to apply the height - but is there a clean way to grab the largest height value from the myCont collection?

$(document).ready(function(){
      $('.myCont').css({'height': newHeight });
});


<div class="myCont">some text</div>
<div class="myCont">this one may contain a whole lot more text that the rest .....</div>
<div class="myCont">a little text</div>
<div class="myCont">some more text than others</div>
