That is how Crafting Recipes work, you cannot specify which Item gives back what, if I let Ingots be gotten back in one Recipe I have to do it for ALL INGOTS in ALL RECIPES, and that would be hilariously broken. Yes the Item dictates what you get back, not the Crafting Recipe, the Item does not even know what Recipe it was used in. Edit: Use cheap things like Bricks for the Ingot Molds or Wood for Plate and Tool Molds.

Big Meteorites are actually “Raw Ores”, which happen to have a Crucible Special Case that lets you process them in there. And ever since I added that Crucible Special Case, I also added one for Ore Blocks too, though that one is still inefficient, because in both cases you get one Ingot per Ore.

They actually have been buffed to be equal to Coal Gems for Torches, they were four times worse before. And most of the time the sentiment on Rocks is “if you have to use them, sure you can, but dont use Rocks otherwise”, which this is perfectly representing in those Recipes.

There is ways to disable vanilla Ores in the Worldgen Config by just disabling the Ores themselves that are Listed in the “Stone”-Stone-Layer (yes I actively generate them in there for Compat reasons). The DisableVanillaOres Config is ONLY to disable the original way those Ores generate, and has nothing to do with the Vanilla Ore Blocks themselves.
Hope those bits of Info helped. ^^
