2006 rxp cam swap

[esse77]

I’m swapping in a cam from an 04 rxp to my 06 along with valves and an et137. I’ve heard that I need to drill out the oil restrictor in the rocker shaft from 2mm to 3.5mm. Can anyone confirm if that is correct? And if it is where do I get a drill bit hard enough to drill
it?

I hope your not moving stock 04 valves to your 06. They are aftermarket ones correct?

Yea the valves are a set of riva performance valves with upgraded springs and retainers. I’m putting the 04 cam in for better valve control and heard that if I decide to spin more rpm I have to drill out the rocker shaft oil restrictor to get more oil

You really don't have to drill it out, but if you choose to do so you will need to use a diamond tip bit.
