Not Ranked
I don't want to sound negative, but I do not think that having the heads port matched is nearly as good as a full cnc porting. You had asked the question as to how much power the motor would make at 6200. If this is where you want your motor to peak you will either have to have the Vic jr. Heads cnc ported, not just gasket matched or change to a different already ported head such as an AFR 205 or 225, or better yet a TFS High Port.
As is your combination will most likely peak around 5600-5700. If you are happy with this and this is what you asked for when having the motor built, then you will be very happy with a very nice piece that will serve you well. If you intended to get closer to the 600 hp number, then only a couple of items need to be changed or modified, and it is easier to have this done now then when the motor is in your car.
I have made a lot of changes to my set up, and I wish that I could have put it on the dyno the first go round instead of doing it later.
