GW’s website, they might have cut him, no idea; he still has modern rules so I doubt it. I made my own counts-as a few years ago)
Marine heads are almost entirely interchangeable. One caveat is that some, like the beakie Mk.
VI, might clip with the gorget. So feel free to use old helms on the new guys.
On that topic, shoulder pads are similarly compatible. Old power armor pads fit intercessors/hellblasters/etc, while
TDA pads work for gravis/agresors/inceptors.
I will come in and add a few more examples of non-interchangeable marine heads
Deathwatch Veterans wear Mk8 armour and even regular helmets clip the gorget. You need the special "smushed" faceplate that comes in that set, or bare heads.
The Mk8 chestpiece that comes with the Tactical Squad, as well as the old tactical squad, has the same issue. Mk7 helmets just about fit but look bobblehead.
