LA360 initial timing too high - are there different timing covers?

Thanks for up dating this thread. To many time a problem is fixed but never reported back. Which make at thead useless for future reference.
This is now, a great thread for someone who want to put a performance cam in,.... But hasn't learned or isn't aware of the pit fall that could happen.
You have installed the performance cam that "fit" your combo. And without driving it, you are already happier.
I bet your "butt" odometer says it faster too!:)
