Piker Porting (Intake Manifolds)

In your bottom picture you can see the divider wall heading off to the left at the bottom. I would grind that area until it wasn’t heading to the left like that.

I wish I had something out in the shop to show what I’m saying better.

As soon as the wife gets back from town I’m going out to try out my new cutters.

I understand what your referring to, reduce the bottom and top “inside” wall of each divider and if needed, “maybe” reduce the middle of the outside of each divider wall to get them straight.
