I couldnt tell ya got some guy that previously worked at kelford cams to do them. he said he didnt make much $$ on the job, quoted me $600 or around that amount to do them and spent 3 straight days on them
yea nick after reading that thread he said there was no plating and that it was just polished.
seams like a waste to me .... cleaning brought mine up pretty good as ya can see and if you ran e85 it would burn clean anyway.
I remember reading somthing about surfaces being ultra smooth can be a bad thing also .... bugged if I know
