My cam has XE lobes from Comp Cams which are a little agressive, but , the lift is only 555.
Thanks again for the help.

How in the world would I find out if I have one of these bad batches of springs?
thanks.

I'd recommend , if you're curious about it, just pulling your valve covers and looking to see if you have any broken springs.
