4.0 cylinder heads

i am looking for a set of assembled aftermarket heads because mine are worn out and cracked, best i’ve found is King Cylinder Heads, $325 per head, if anyone has already bought a good set for cheaper let me know where!

Hello first time posting please help all advice is welcome, I have a 96 4.0 ranger, about two weeks ago I had removed my cylinder heads, the reason was I loosing rad fluid and had visible smoke from exhaust ,I could see a visible crack on the passenger side between the valves on the #3 cylinder...
