intake question

I agree. Can you port the intake. You just need some machinist die and a scribe to mark out the gasket size and start going in on it with a die grinder and buts as deep as possible.

Combo dependent, adding a open spacer on a dual plane helps from the mid to the top end. Milling the divider is a very similar move but will also help in getting the die grinder bits in the plenum area.

The Weiand’s are capable manifolds and get really good when ported. While nothing beats the RPM now, but since you have the Weiand now....
