Ebay crf230f upgrade cam and roller rockers for 165fml

I've been eyeing some chinese performance camshafts with roller rockers on Ebay for quite some time that are for a crf230f. For about 50 bucks it seems like it would be worth a shot for my zs165fml motor. I'm trying to gain a little more top end grunt for highway riding. It will hit 75mph with current setup and I usually keep it to 60 or 65. I'm fine with the top speed I would like a little more acceleration for passing power when going up hills and against wind gusts and such. Anyways I'm wondering if anyone has used these cam setups with stock valve springs or have any recommendations for springs and cam timing etc.
