Looks like you will need to trim the intake where the valve covers sit too. If you run aluminum covers you have to. The Victor is made for a wide variety of heads so it has a ton of material on it. It's like a trim and cut to fit.
The Northwind(KRE) will need less work and is a little shorter.
If you need .060 you split that to each side, and take the gasket into consideration.
