Ghost AMR Plus Geometry Question

I am planning on running some Marzocchi 350 NCR's which are 27.5 on my 26 wheeled AMR Plus and have a question.
Stock it comes with a 150mm Fox Talas fork with 39mm offset, this gives a head angle of 67°. A couple of articles on the net suggest the frame was also designed to run up to 165mm forks which I calculate would give a head angle of 66.32°.
The 350 NCR's I calculate would give me a head angle of 65.32°, which isn't ideal (or is it) how much of an issue do you think this would give me in terms of extra frame stress and handling.
Of note the stock trail with Talas fitted is 102mm, with 165mm 26 forks I calaculate the trail to be 107mm and with the 350NCR's fitted it would be 112mm.

Why not drop the Marzocchi forks to 150mm?
Marzocchi only sell 20mm spacers to drop it to 140mm but take the spacer to any engineering machine shop and get it shortened to 10mm. Should cost you about £10 for cash.
I dropped my 350 to 150mm with a spacer I turned down myself in a lunch break.Transition Patrol - viewtopic.php?f=10017&t=130702350
