New valve gear - choices

Hi all,

Researching the replacement of cam, lifters, pushrods, rocker shafts and timing gear.

had a good read of RPI's site and dedided to go for it at 160k kms and no apparent noises yet.

My questions are:

* Is the Piper extra torque cam shaft more durable than oem?
* Is it always necessary to replace the rocker shafts, and also the rockers?

I'll take a little more torque from the Piper, but I'm really intersted in durability.

All comments welcome.
