Porting 600 CFI-4 2007

[Dan Dtek]

Hello,
I'm Dan from Quebec City, I have a 07 IQ 600 CFI, I would make a porting in my engine

. Is there anyone who has already made a porting in this engine? I have questions. I measure a duration of 197 degrees and 127 degrees, exhaust and the intake, stock cylinder. Which gives me 72 degrees (197-127). Normally I passed not 70 ... because this motor not well filled and less torque. If I shim the cylinders .125'' I spent 212 and 143. That would give me 69 ... I should have an engine with more torque and hp ... I would like to know your opinion ...
thank you
