If my heads require milling I always have both surfaces milled and have never had any issues with intakes fitting.

agree, its not like your taking 1/2 an inch off or something. I milled my current eddies down to 57cc to get more compression using the stock 360 pistons. Airgap intake fit just fine. Never had an alignment problem worth worrying about.
