All you really need is a good accurate steel ruler . . . you lay it on edge and then see first of all if there is "light" coming through anywhere on the head. You can use a feeler gauge underneath it to see the level of warpage.
Do this in a few directions and you'll soon know if there is any appreciable warpage. You'll probably find that your heads are fine.
