Yea, I can understand the header primaries covering the exhaust port, and I'm sure with a 2" tube it would probably cover it fully, though 2" on my "relatively" stock ( L78 cam with solid lifters) BB would probably kill my bottom end. 1.75" would be the way to go, though I'm thinkin' the flange will cover part of the square exhaust port and cause turbulence & flow concerns.

An exhaust header reduces exhaust back pressure by providing a separate exhaust tube for each port on the engine. This increases the air flow of the exhaust which can increase gas mileage and horsepower.
