hi traces are a bit noisy (nothing to worry about) might try filtering
cant see anything wrong with the coil secondary ie i can clearly see the coil oscillations but the critical information like the pull down to ground charge time and spark line are not visible you need to alter your time base (sweep)to give a clearer picture.seriously take a look at james dillions scope book its not dear and its packed full of useful wave forms and scope set up.
however i still think you have a cam timing issue either belt slipped a tooth or the hydraulic tappets are to opening at the correct time due to lack of oil pressure.
seems like a bit of a head banger don't lose heart
