And just like that....Dany's race engine is gone!!

It still seems like you have 15 valvesprings you can reuse:D
Just kidding.
Good to see that you had a replacement engine available when it was needed!

Noticed that you seem to have a bent pushrod in the background in the valvecover,how does that go togheter with the broken valvespring?
That bent valve atleast seems to be a good testament to the quality of the valves,that could easily have been a broken of valve making more damage..
Looks like spring broke, then the valve hung open and pushrod fell out catching the outside edge of the rocker, then bent on the next cycle.
