Would I be righto to remove the cams how it sits then wind over to tdc ( or just past) and install the new cams?

I have began to remove my camshafts without first putting the engine to no.1 tdc . I removed the timing belt and when removing the vct gear the camshaft turned a small amount. What is the possibility I have pushed a valve into a piston and damaged it? I felt resistance that I am assuming is just compression but want to be certain I haven't damaged a valve.. Also now that the engine is out of time how am I to get it to no1 tdc without and valve/piston interference
