I went to KH for fitting because i bottled it ( and there labour rate is £55 ph) but in hind site i think its not a hard job for anybody with average spanner sense! the full instructions come with the cam kit with all loctite supplied and new woodruff keys and gasket's and seal's , take your time and all will be good i recon flag
I can't see any reason why anyone would not be happy with the results! but it takes all sorts cheers
