450 SL bent valves

Yes, I did reinstall the oiler tube across the top. I also cleaned out the oil tube in the head and checked for flow from the oiler tube. On the first rebuild several rocker arms were quickly worn down due to lack of oil. Cleaning head oil ducts corrected that problem. I just called the machine shop that installed the new valves this second time and they did check the head for warpage and there was none. I tried turning the left cam by hand and cannot turn it. I can turn with BIG pliers. Right cam turns much more easily. I was assuming problem was the valve springs I was compressing. Head and cam towers are all bolted down now. So, this could be a bent cam??? Can they be straightened??
