Ebay crf230f upgrade cam and roller rockers for 165fml

I just ordered the ebay camshaft and silent roller rockers kit. I bought one with an "upgraded camshaft." It should be in by the end of this month. I plan on documenting the process here with pictures showing the difference between the new and old cams. I will probably do some port cleanup and possibly adjust my squish clearance if there is enough valve to piston clearance. I should gain some power and efficiency there. I'm going to steer clear of any changes to port geometry and just do a 60 grit finish on the intake side and blend any sharp edges I find including the combustion chamber. Oh and if anyone has any torque specs they would like to share or possibly point me to a reliable source that would be awesome! Hopefully this will help someone else decide if they want to try to bend a valve in their engine. I hope the stock springs hold out.
