Even if the intake, Aluminum, is polished; it will dull. Aluminum oxidizes and dulls. Just the way it is.

When I said you install intake without gaskets, I meant the end gaskets on the intake. Intakes have four gaskets....one on each cylinder head that seal between the intake manifold and the cylinder heads. These two gaskets you need for sure. It seals the intake ports, water cross over, exhaust cross over and oil from leaking. But, on each end of the intake manifold, front and rear, there are two cork gaskets, one on each end. These two gaskets are there to seal the intake manifold to the cylinder block to stop oil leaks. Most people that install aftermarket intakes use a bead of RTV. RTV stands for Room Temperture Vulcanized silicone cauking. You put a bead of it down both ends. A little extra dab where the intake side gaskets, on the cylinder heads meet the block. Let it sit 15 minutes or so, till it starts to "skim" over. Then install the intake, straight down without moving it around. Just nice and straight. You can use some home made studs, to assist in the alignment. Get four extra intake manifold bolts. Cut the heads off the bolts and cut a slot in the cut off end with a hacksaw. This will allow you to unscrew them, with a flat blade screwdriver, after you get the manifold on. Torque the manifold from the inside out going side to side. Not TOO TIGHT.

A four barrel will burn more fuel, but to make more power you need to burn more fuel. That's just the way it is. BUT.....if you drive normal and like a sane person....you will more than likely get the same mileage or even better if you keep your foot out of the back barrels.

Hope this helps...ask away.

Have a good day.
