One set NOS GCM race cams, for F1, TT etc. Lift and duration probably similar (this has been covered in this site more than once) to NCR 7 and/or Montjuich cams. Need +6mm static valve clearance to work. Were installed in NOS F1 heads, never run, and then replaced with 900SS cams (see the Laguna Seca replica). $600 plus shipping cost + 4% PayPal. MikeV
