What to expect from aftermarket headers????

I have had a beautiful set of GHL headers (w/heater boxes) sitting in my attic now for 3 years (impulse buy). I have not installed them because I have questioned if the factory 965 exchangers are nearly as good.
What should I expect from installing these. Here is a description of my car.

1982 911sc narrow body @2675 lbs with out me in it.
Engine is a a factory 965 3.3 Turbo S engine (rated @370hp)
The turbo S engine has different cams and heads. I dont recall if its the same turbocharger but recall its a K27 7200.
I added a modified fuel distributor and run the boost at 1.2 bar with excellent a/f ratios and exhaust temps.
Aside from the fuel distributor the entire engine is stock. Of course the 965 muffler and cat were swapped out for a large single outlet stainless B&B muffler. Wastegate has an open down pipe.
The transmission is a 1987 G50 box with very short gearing.
Full boost comes in around 3000 rpm with current configuration.

Will I get any worthwhile reward from installing these GHL headers?
