exhaust manifold drain plug removal? what size allen key are they?

quick question on the exhaust manifolds how do you remove the drain plugs .what kind of tool do you use. and in my case they look like they have never been removed .i am thinking i might have to pull the manifolds and use some heat is this a doable idea?
can i put heat to these things, i have never had them off yet and don't know what they look like on the inside .
i am the new owner of this old boat. ,i am also new to inboards . so i am learning as i go .

thanks jake
