You can't really remove much more metal in that area or it will break through into the oil galley that feeds the followers. These intake ports have a funny shape compared to most OHC heads. That part of the port is the roof of the intake port. The port comes in straight and then turns up. The cross sectional area there is pretty large stock and does not need much work unless you were to put a larger valve in. The same goes for the floor of the port just a little further in I would have liked to remove a hump in the floor but could not because it would break through were the injector boss is. Ideally I would like to make the port as straight as I can, but GM most likely for dimensional reasons could not make the port that straight and maintain hood clearance.
