63 Dodge Dart, now let me see;)

Ok, I need a little help here, I'm confused on the cam/crank timing. Can I get the cam 180 out? If so, how do I figure it? this is really hurting my brain and I don't want to ruin a valve. Even though it's a non-interference engine (so I've read), still worries me, especially with the shaving of the head. Once I get that figured out, I'll remove the rocker assembly, and lube it up. Thanks
