Well I had a Missfire.... after Santa dropped off his stuff (new plugs and wires) Miss fire continued. Off with the valve cover and the photo tells it all.

These are the comp cam dual springs ... cant remember the model but got them the same time i put the cam in the car about 3 years ago. Car was warm and at low RPM when miss fire started... Cam has just over 600 lift

The good news is that it didn't drop a valve, the spring did its job.
Yes... very good thing ... I was at low RPM, mid march I will be back at VIR with 10 / 10 ..... not sure if outcome would have been different at 6500 .....

That may not be the source of your missfire. I had a similiar problem last spring. Mine went so far as to have the outer ring of the keeper break off, and another spring crack (installation problem-long story).
The car did not miss or run bad in any way. It did sound like I had a very bad lifter or broken rocker.
From: Dear Karma, I have a list of people you missed.

Mine ran like crap you could tell it was missing .. then the check engine light came on ... code said misfire.... knew I had a couple questionable wires so replaced them and still had the misfire... I then pulled the plugs and one looked wet or a darker wet brown like it was not getting the fuel burned off. pulled the valve cover and saw this .. I sure hope this is it
