Earl, chttp://www.jet-hot.com.au/ I could have Jet-Hot applied for you but will give you the link to save you a few bucks shipping costs. They will take manifold as is and do all cleaning etc.. I would recomend you do any gasket matching first. Also remember all aluminium manifolds require gaskets made for alum. not same as iron manifolds. Before install just scuff gasket surface with Green 3M pad or 280 grit paper.
I have many parts done, the brake calipers are another must do for us and helps with heat as well as looking brand new for ever.
