i read some where that you were going to try out some ported heads from different shops, just wondering what you found,

I am about to put a stage 1 cam and 11;1 piston in my raptor, is it worth the money to port or should i weight untill i go big bore?

Is porting hard, i do all my own work, pretty good at this stuff, is it better to leave to the pros?
