looking for. As far as taking off the upper plenum, it' s pretty simple just time consuming, I believe some guys have a tech on it (search). But, I can polish your plenum if your looking for that, I also offer port matching as well. Check out my classified ad for some pics of previous work. Also, you can polish or chrome. Chrome is a process that you can probably get done locally, it's called electro plating and is somewhat expensive. Polishing involves actually filing down the plenum then polishing and buffing it all by hand. It is very time consuming and cam be costly. I don't really charge that much but I do require some down time. For a polish about 2-3 weeks due to the 40+ hours of labor I have to put into it. Hope this helps.
