RE: questions on roller rockers

The roller rockers should take care of the upper part of the valvetrain.
Since it's already a "Roller Motor", you don't really need to worry about
the valvetrain unless you're planning on running at the 6000+ RPM range.

With the 1.6:1 Rockers, you don't need to change the valve springs. With
the 1.7:1 Rockers, it's recommended to change the springs. The hardened
pushrods aren't a bad idea though.

Subject: DML: questions on roller rockers

Now that my dak is pulling harder and higher in the upper rpm band (I'm
shifting at 5200 - 5500) I'm starting to worry about the valvetrain. I'm
thinking I should upgrade to some good roller rockers, maybe stiffer springs
and some hardened push rods. But I don't really know where to start. When
you do roller rockers do you change anything else (springs or rods)? I want
to make things as safe and reliable as possible for higher revs. So what
should I do?

Thanks,
