If anyone else is interested in doing it to theres here are the instructions on how to go about it.
1st you need to remove that ugly black rocker cover and the crapy gasket most came with the old style cork gasket with the 2 rubber block on either end of the cyclinder head you will need to get e new one but try and get the new big rubber gasket which has the rubber blocks included into the rocker cover gasket these gaskets are the best ones to get they can cost from about $30 up to $55 from your Ford dealership.
2nd you need to get the strongest engine degrease you can get your hands on and a scrubbing brush then apply the degreaser allow to soak for about 10 to 15 mins then scrub the whole rocker cover really good then spray more degreaser again then scrub again then spray again then allow to soak for another 10 to 15 mins then using a high pressure hose nozel wash all the rocker cover really good once done allow to completely dry in the sun or over night.
Part 2 will be tomorrow stay tuned.
