No mill, No W2 adapter plates, No problem

You can see on the right center port that’s out past the port on the head....... it appears that the hole in the plate is shifted closer to the adjacent bolt hole than the other one is.

And it looks like the two outer holes are shifted in the opposite direction.

here’s a better shot of the port without the plate. As you can see this get removed anyway. That lip is already taken off by me on the left. The center exhaust ports on Edelbrock, speedmaster heads really need shaped.
