One thing you should do, weld on a new flapper and then port. Porting to the size of the stock flapper will help but still will not flow enough for an open exhaust and intake.

also, is it better to go with an external wastegate?
if so, where can i get one for fairly inexpensive?
will it be extremely loud, or will you not really be able to hear too much of a difference?

Also be careful of the bushing on the WG.
I think when I ported mine I bent the flapper rod a bit which made it have a small spot stay up and open. This would have created a boost leak,
BTW Series 5 hotsides are impossible to find!
If you have the hotside off check for cracks.
