I like the heatshield over the manifold and the heat shield on the air inlet pipe. What you have done with the rocker breather is just fine, looks neat, and will do no harm. Sadly it is not the main cause of inlet valve/ inlet tract fouling. Mr Ford in his infinite wisdom also runs second breather pipe to the underside of the inlet manifold from the crankcase. For some reason I cannot put a pic of the pipe in this post (I keep getting a massage saying it's over one meg but it's only 300k)so I'll put it in the Morgan Gallery. To stop the crankcase vapours properly (which is a VERY good idea) you need to trace this pipe and remove it from the crankcase. Remove the "anti-backfire" one way pcv valve if fitted (which is actually just a ball bearing and a spring in a tube) and replace the tube in the crankcase, running it to atmosphere or a catch tank as is your want. Then do not forget to plug the inlet in the manifold. Hope this helps.
