ok, im streetporting my n/a 13b and im working on my exhaust ports now, i lined up the template from RB and it looks like the template is saying that the port should start lower than the tunnel in the housing goes and i would grind into the water jacketif i went straight outward. I was just wondering if im supposed to start the porting heading upward at thos point, or if for some reason the i have the template too low, altought it was aligned with a straight edge and dowels as the instructions said.

Thanks

port match the port to the exhaust sleeve and then port the outline to run into your port matching then bevel the inside of the port at the trailing edges for apex seal clearance.
