What Intake gasket

What intake were you going to use? You may or may not have a lot of choice, set the intake you have on and see how much room you have between the head and intake. Your not going to pull the heads to match the intake, it will run just fine. You should see how off my 318 ports were, I just put it back together the way the factory did. It will be fine. Just get the gasket set that will work for you.
