Fel Pro Intake Gasket - 1256
Guys,
I am going for try #2 to put my intake back on. Using Black RTV this time instead of the cork. My question is regarding these metal inserts in the center water port, it appears pink in the picture. Do I need to open these up, or do I leave them as they are? Why do they narrow it down so much more than the opening in the manifold and heads?

If you're running emissions and your manifold supports EGR, or you have a hot air choke (and your manifold supports it) you'll need that.
It's also there to prevent icing - do you drive in really cold weather?
Otherwise, I'd recommend leaving it blocked.

At least leave the restriction in place.
Be sure and wipe the end rails where you're going to use RTV with alcohol or something to remove all traces of oil. RTV won't seal if it can't stick.

Keeping the heat out from under the carb will make it a little more temperamental when it's cold, but results in a cooler fuel air mixture which is good for performance. That's why they came up with the "Air-Gap" manifolds- to get the heat away from the carb.
