Oil Gallery Plugs

I am stripping my engine in my shop class and i need to take out the oil galery plugs to have it dipped. Is the size 5/16's? 3/8 to big and 1/4 to small its not like 11/32's is it? and in the engine kits do they come with new ones my teacher says yes but i was thinking (again he more ford/Chevy guys, where do they get these teachers :P ) perhaps its different on mopar for some reason like in my example of "yeah its ok to run with out a kick down linkage" and from on here (mopar guys) saying woah hook that up.

also i have a factory console for my car but yet there is a b&m shifter in it(none ratchet) should i go with console it has no door for center holder for stuff) i like the aggressive look of the b&m but kinda like the factory shifter console and the fact i have more places to put stuff,
