[Mgs] Piston Broke (was Picking a head)

If that is true then your engine builder did you no favours.  I see  this all 
the time - overkill on valve spring pressures that end up putting  
unnecessary premature wear on the valve train.  If your engine has a  power peak at 5500 
then 6-6200 is all you need to 'spring' it to, although some  sort of RPM 
limiter can be nice - not much of an issue for you, as the valves  should just 
float without hitting anything.

I was  told she could handle 7000 revs but never really found any  
advantage  going much over 5500 - it was only the odd error that would  
see the  needle bounce that far past the old redline.
