Piston, cam, and porting?

Can I get a quote for a trail port? I am building a 660 based 720. I am going to run either an x4 cam or my stage 2. I will also need a cp piston to match it in order to make the most of the compression ratio (tbd by cam though).


BTW- I'll be running a trinity intake and 39mm fcr's
