Porting Question

there's water under the roof kink, usualy the roof kink doesn't hurt the flow much (2-3 cfm in my testing). The best gains are a good multi angle valve job, an aftermarket tulip shape stainless valve, blending the bowls, and radiusing what little shortside there is.

There's water around the whole port,so what.
After bowl and short turn work...the flow numbers jump with straightening the roof..they can go from 145/155 to 175 or more.Thats what happens on my bench
