Before you get too carried away, make sure that the engine will accept the AX-15 input shaft.
While it's true that the 9.2Scr 5.2M will tolerate a cam change better than an older 8.0 Scr 318LA; in a heavy truck, with a manual trans, you cannot really afford to have a soft bottom end. So the advice here is to think about it first;
If the heads come off I would measure everything to get an exact Scr.
If the heads stay on, I would cc the assembled chamber by measuring the volume using a thick oil, with the engine suitably positioned with a sparkplug hole set to be the highpoint. This will come in handy to know, when it comes time for a camchange.
