My understanding is, in order for that spacer/sheer plate to work as designed, the manifold needs to be opened to the full size of the opening on the underside(same size as the gasket).
Looks like it needs some time on the mill to get it roughed in.
Exactly. If OK is going to run that shear/reversion plate (he should) the intake manifold needs to be machined so that the entire opening of the plate exposed to the plenum. If you not, it will not work.
