How much HP adding a K27 and headers

wcc, hope you don't mind but I am curious.

We will be installing a full GHL header system and a K27 to Bill's 87 930 this weekend. The car was fast already just mostly stock.

What kind of HP gain may be possible with this upgrade. I think he has an .8 bar boost spring it and that,will remain, I think.
