Thanks! I´ll do that.
I´m only looking a little more power over stock ports.
My first plan was to send these cylinders to Fast or HJR and get them dune/play or Trail ported, but then I was reading over here that they were so busy that it would take 3 to 4 months to get them back. That is too long for me to wait.
I found one pro over here in Finland. He promised anything around 60HP and good torque, but he also told me that he wasn´t familiar with these cylinders. He asked 600€ (895$) for the job ( porting only).
