Need cylinder head/ cam towers
 

So my cam bolt has spun loose and my cams have overheated. I have my reading up on it and I'm not sure if I can just replace the cam towers/cams or if I have to a get a new head. Any info on what to do would be helpful. I am looking for either a cylinder head or cam towers ( if its possible to just change them ) I have checked the head and pistons and everything looks ok I still want to bring it to a machine shop and get it checked but hopefully it's ok.

i have a mission critical performance cnc ported head with supertech valves, valve springs, retainers and guides. it does not have cam towers though

I have an AP2 head with everything included on it. (cams, cam towers, valves...) It has roughly 57k miles on it. PM me an offer and we can work out a deal.
