Since I have found the templates SIMPLY DOESN'T WORK ( If I have to cut everything the template says me will be cutting the valve seats too specially in exhaust ports ), I went and made vertical grind job from inner valve seat edge up to bowl, blending the valve guide area to this.

Can I see your jobs on this ? specially intake. I'm afraid I could grind excesivelly on intakes ports and get really close to water passage areas making this vertical wall.
