Ceramic coating on the outside of the mani wouldnt that trap more heat in and make the internal temps hotter?

That's why it was mentioned that the internal bores should be done as well, and that is standard procedure for a proper ceramic coating shop. DIY projects probably won't have the ability to properly coat these areas, however.
Someone please clarify for me if they have actually managed to switch to the later model exhaust manifold on their early MKIa's. That is, did they manage to switch to the manifold with the egr outlet on the side of the #4 outlet, instead of on top, and get it to hook up to the original egr valve by just installing the later egr connecting pipe. I wasn't sure this could be done, as I haven't had a chance to look at any late MKI's except for my SC, and I had assumed that its EGR valve might have been repostiioned enough as to make the changes on an earlier MKI unfeasible, and I didn't know if the late MKI's had the egr valve in the same location or not.
