Replaced all 6 injectors, now leak test still fails

From my understanding, Cummins doesn't sell cups for the head. You have to replace it unfortunately. Rawze mentioned on his video some shops will try it. But at a million I'd just bite the bullet and Inframe it because most of the labor is done once the head is pulled and also just for peace of mind. At least do the bottom end and a reman head.
