So if I get a sram force gxp crankset it will fit the mega Evo bottom bracket on the bike?

No. You will need a new bottom bracket to fit the shorter length SRAM Force 1 crankset spindle. The FSA BB is a strange 86mm length which requires a longer spindle. You could use a FSA carbon crankset if you don't want to purchase a new bottom bracket. The SRAM GXP BB utilizes the standard road length of 68mm and is threaded.

Hi, After a year or so, with the Flow Stem on my 2015 Sirrus Carbon Pro, I'm back on the search for a replacement ... can anybody advise a replacement headset, so I can fit a 'normal' stem, rather than the flow version I currently have ?

I have a 2016 X1 model. You don't need anything special to not use the "flow" stem. Your bike should have come with a FSA conical spacer. You can use any stem you want. Just take off the flow stem and spacers, put on the FSA conical spacer and however many regular 1 1/8 spacers you need. I ended up changing mine out for a specialized 24 degree comp stem and drop handlebars.

Hi,
The problem is that the bike didn't come with a FSA Conical spacer, and I have yet to find a suitable one that will fit.
That is my only issue .... if you have a part number for the spacer you have, or can point me in the right direction, that would be great.

Unfortunately, I do not have a part number. The next step I would try is to stop by a bike store that sells Specialized bikes and talk to one of the mechanics. They can look up your model bike and know exactly what FSA headset the bike uses. Once you know the model number, they can order just the conical spacer/dust cover that will fit. I can almost guarantee the model is going to be one of the most common headsets FSA offers.

Also, tell them you never received it in your "new owners pack". Mine was in with the instruction manual, owners manual, bleed blocks, etc.
