5.3 ls head.

[V Remian]

I am working on a 5.3 ls type head and the flow gets noisey and backs up @ .650.
I discovered by accident if I put my index finger in the lower left hand corner, as if I were pinching that area, the flow gets quiet and the numbers go up.
Poking around with a "flag", the shortside shows no signs of separation.
Anyone willing to impart some advice?
Also, the port does this with the intake on as well as with a radius.

Thanks in advance Vinny
