Wow! I didn't see the secondary ports when I made my comment. The way you have opened up the secondaries, that later closing on the primaries won't make any difference. You might as well leave it alone (what is the point of closing the primaries when the secondaries are still open).
I thought this was more of a daily driver, my apologies (I should have seen the HBP in the title - I thought this was a ported S5 NA).
Good luck with the build.
Get some dyno numbers, I would be curious if you can get 200WHp out of this build.
