Porting Edelbrock RPM Air gap to 1206 gaskets part 2

I have Flotek 220 heads CNCed almost perfectly to the 1206 Felpro intake gasket. The Air Gap I got has core shift and was made for the 1205. Here is my second video of porting it to match for my 406 SBC build going in my 1975 C3 Corvette.

What heads did you use with the 1206 gaskets? I use a 1205-S3 and its about perfect for mine with 190ish cc runners on the heads

Dont forget to install a 1 inch carb spacer plate on top of that manifold to raise those carburetor butter flys above the tops of those runners , it good for around 5 to 8 horses
