Porting fast 90 intake....
Porting fast 90 intake.... I took the intake apart and know the obvious places to start with the ridges in the runners. Where else can I port to pick up some extra power?
It looks like they may be some areas at the beginning of the runners to reshape and remove the seem to pick up some flow.
Is it worth (or possible) to port the whole length of the runner?
Advice and pictures would be appreciated. Thanks.

Here's my opinion. Take out any casting flashes/ridges. Portmatch to the head and gradually smooth back about 3-4in. The plastic is very thin close to the injector boss so be carefull there.
