Is This Normal (pics) Doing a FAST intake swap and saw a lot of carbon?, in the intake ports of the heads. Is this normal with a set up like mine (sig)? First picture is with 6K miles after heads and cam install. Second picture is of the stock heads and cam with 19K miles. Thanks

It's 100% normal. It's oil that comes from the pvc system and then moves it's way into the intake runners. If you take your heads off the combustion chambers will look the same.
