I pulled the engine and cleaned it up with a wire wheel then I painted the fins with some high temp engine paint. As you can see in the pics I pulled out all of the horrible stripped out phillips head fasteners and replaced them with stainless allen heads. I also found a plug for the starter from MG innovative products, I could have built it myself but I got lazy, it is actually a nice piece and their service is really good.
Since the engine ran pretty well before I pulled it I am going to leave it as is internally.
