Do not port to the gasket. The AFR heads have the same width and height as the 1250 gasket but the corners of the AFR heads have 3/8" radius corners and the 1250 has much smaller ones. Wait till you have the heads and make a template off the head to put on the intake for scribing.

Port the intake to the heads, not vice-versa. Yes, the AFR head has a slight bias to one side of a stock centered runner. Make the template of the head, not the intake and use that on the intake.
