You just racing emra mate?
it is worth putting them cams, as long as they are ok, into a standard engine.
Phone chris at dynoproracing in runcorn, http://www.dynopro-racing.co.uk/page_1228983208953.html
tell him Jake sent ya. He is good with the zxrs and not far from you, good results and very reasonable prices.
