One thing you will want to plan for is cleaning the ports in the head if there is carbon buildup. You don’t want to disturb that sediment and have a chunk break off and brick your engine, doesn’t take much to stick a valve open just that tiny bit.
People have recommended closing the intake valves by rotating the engine (verify with valve cover off) then using making tape, long scrapers and pipe scrubbers from harbor freight and compressed air to clean all the carbon out to clean the ports before just slapping the new intake on. I would also recommend new hardware for the manifold and of course a new gasket.
It is also near impossible to remove the manifold without removing the EGR so plan for that as well, not only will you need to re-route coolant hoses if you delete the EGR but you will also need to account for the fact that there is no longer an EGR valve for the vacuum hose to attach to.
Finally a lot of the race pipes out there are not optimized for the AHU. If you are sticking with the stock boost piping, it is slightly smaller in diameter (around 51-52mm) than the average race pipe OD of about 57mm. This prevents the use of which stock boost rubber elbow. What you need is a 45° boost hose that also steps down the two sizes. Here is a link for the one that I plan to use, eyeballing it it seems to match up. You’ll of course also need appropriate hose clamps...
