Can we install valve springs and spin to 7500?

I also read that 7k is safe for stock valve train

The L61 won't support more than 13 PSI on stock valve springs. Nor should you be going over 7400 with stock valve springs.

Just get the 78lbers

I doubt it, I'm spiking 16 and holding 15 with my 2.9 set up. No problems at all here. I'm auto as well. (knock on wood)

Hows the auto holding? What RPM are your shifts at?
