correct, we are releasing a new 2-bolt header for the current crop of bolton up pipes and of course this stock location EFR turbo kit. Paul at Yimisport did some preliminary testing and we're just about ready to put photos online, a few more final tweaks

correct - i will ask the webguy to make a note of this. Also two more small things you will want to be aware of:
a) coolant line orientation (inlet on bottom, outlet on opposite side top)
b) the oil drain/turbo clocking position will be dictated by the wastegate bracket! (only one position where it is truly "happy" which you may have already found out)
c) lastly -great to see you applied antiseize to the threads (for good measure its also a good idea to apply to all vbands/threads/nuts also)

Clearance is tight on all the nuts, but that one is the tightest as the WG path "cuts the corner. It definitely makes for a really smooth WG path. I never really looked too carefully at the WG path on the VF turbos, but when I saw the EFR, I compared the WG path to the other turbos I had lying around... yeah, no wonder people have boost creep issues with the stock turbo...
correct- the EFR's aerodynamic wastegate port gains power by massively reducing turbulence at the turbine wheel's exit. Our inconel locking hardware is tall due to the locking portion of the threads (and not cheap) but the advantage is you'll never worry about them coming loose
