You may have a new head, but the old head may have done some damage to that cylinder. Top end damaging bottom end. A cylinder "leakdown" test is really the best comprehensive test for isolating single cylinder problems.
How long do you think you ran the engine with the cracked head?
Unfortunately, replacing the cylinder head is not going to remedy any issues that cylinder created with the bottom end of the engine. It really is not that uncommon.
