right on dude! if you ever pull it apart take some shots of that porting work and do some measurements... I'm always interested. Nearly every guy ports differently.
having a ready to go GSS motor as backup aint bad either!

I found the exhaust port to be really different. I'll snap a pic for ya in the next day or 2 when I go to throw it on. The intake looks normal, no extra holes, just enlarged boost ports.
