break the edge on the exhaust ports. you will notice a little bit of a chamfer on the stock ports.....mimic that on the new ones or you'll have problems with the apex seals in the future. you don't want to have such a sharp edge where the seal travels across, especially when it is closing the port.

You might take the noses out a little further for a tad more free port volume without changing the timing . . . but the volume looks big enough anyways to not make it much of an issue.
Anyone care to explain the assumption that taking the tail of the port down causes more overlap? The back of the port is the opening edge that effects overlap . . .
Here is my first try at porting (went in to the oil track by accident):
