Side note, if your AP1, I would not use 2 step before upgrading that valve train!

whats wrong with the stock valvetrain? Are you referring to the stock intake valves on F20Cs?

Retainers, valves, springs, the works, from what I have read the f20 is notorious for dropping valves in high HP applications, especially on 2 step

I think its the exhaust valves that take the brunt of the force on 2 step, but i could be mistaken.

Interesting. Ive always read about it, just never say any facts...still havnt. I know the retainers on the intake valves are prone to crack from the inside out, which Ive replaced...
