Port and Polish gains?

[espergre]

I have a 07' 400ex with full hmf ironman series exhaust, 11:1 wiseco piston and stage 1 hotcam. Port and polish seems to be the next upgrade for biggest gains. What type of power increase can be obtained? I am looking for advice on whether or not the p&p is worth the cost. If so what shops are reputable and best for cost. Advise please

I'm also curious what gains can be made from a port and polish. I know C&D does this for $175. Is it worth the money?

the biggest improvement i noticed was a more snappier response... all depends on your porting though.

i did my own based on what ive seen around. should you have the tools and the time, its not all too difficult.

EX Lonerider, can you post more info on how you did your port?
